The servo brake motor is not just with brakes

Servo motor braking and holding brake is one meaning.

Servo motor (servo

Motor refers to the engine that controls the operation of mechanical components in the servo system, and is a kind of auxiliary motor indirect transmission device. The servo motor can make the control speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly, in the automatic control system, used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., and can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

It is divided into two categories: DC and AC servo motors, and its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.

It should be, are you going to buy a servo motor with brakes? I still want to know about it, if you want to know, you can go to some servo motors. There will be some professional customer service or technical personnel who can help you answer, if you want to buy, you can find some related shopping platforms to see.

I also had a technical problem a while ago and went to the official website of Huantong to consult, which is particularly detailed.

Servo motors generally have braking functions, which refers to the rapid braking of the motor through the drive according to the external instructions of the servo system. Brake, generally refers to the electromagnetic mechanical brake device at the rear end of the servo motor, which is generally installed at the rear end of the motor, and brakes the motor and locks the motor spindle through the brake pads acting on the spindle of the motor when working.

The servo motor with brake is to protect the motor when the motor stops, and the servo motor cannot be subjected to axial force, when the motor is not powered on, it will affect the system because of external force that causes the motor to run, otherwise there is no need for brakes.

Main advantages: servo motors usually have braking function, brakes, generally refers to the electromagnetic mechanical brake device at the rear end of the servo motor, generally installed at the rear end of the motor, through the brake pads acting on the spindle of the motor when working, the motor is braked and the motor spindle is locked.

Therefore, the brake of the servo motor is to hold the brake and hold the brake, and its role is equivalent to the handbrake of the car. Therefore, the brake is used to lock the position when the motor stops, so as not to let the motor (due to external force) move.

1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

1. Servo motor.

As long as the operation is cautious, the brake must be released, and the servo has the final say, but in fact, the general equipment is not like this, regardless of whether the servo is running, the brake is released after the equipment is powered on, because the role of the brake in most of the dust potatoes is to maintain the position during the power failure (especially in the case of up and down, there is a gravity effect), and the servo system when it is electrified.

It can be self-locking, unless the special circumstances of the alarm need to be considered, otherwise it is generally powered on and released.

2. It depends on the specific settings and functions of the control card.

3. There is only an emergency stop and power failure, and there will be no jogging; Whether the servo alarm brake sends a signal when the machine is stuck depends on the specific function of the control card.

Brake is the meaning of braking, in the servo motor.

In the field, braking is divided into electric braking and mechanical braking, and electric braking is a servo drive system.

It comes with a function, and mechanical braking is an optional function of the servo motor.

Let's talk about electric braking first, which is divided into regenerative braking and dynamic braking. Regenerative braking refers to servo drives when a servo motor slows down or reaches a target position and needs to be stopped quickly (not de-energized).

The kinetic energy of the motor is quickly converted into electrical energy through the inverter circuit (similar to the principle of the generator) to achieve the purpose of rapid braking, regenerative braking will not be powered off, after the motor is stopped, the motor rotor is firmly locked by the single-phase pulsating magnetic field, so the motor cannot be rotated with general external force;

Dynamic braking refers to the inertia of the motor rotor when the servo drive system fails, emergency stops and loses power.

Kinetic energy is consumed through dynamic braking resistance (kinetic energy is converted into electrical energy and then converted into thermal energy) to achieve the purpose of rapid braking of the motor, so dynamic braking is also called energy consumption braking, because dynamic braking occurs in the case of motor power failure, so the motor can be rotated with external force after braking is completed;

Speaking of mechanical braking, mechanical braking generally refers to electromagnetic braking, also known as electromagnetic brake or electromagnetic brake, after the power off, the brake shoe tightly holds the shaft of the motor to prevent it from rotating, and most of the cases are used on the vertical feed axis servo motor of the CNC machine tool (such as the Z-axis) to prevent the Z-axis assembly from falling down after the power failure.

The brake motor is a motor that can lock the position when the motor is stopped, and prevent the motor from moving (due to external force).

The brake is the brake of the servo motor, and the brake is also called the holding brake.

1. Holding brake: It is an electromechanical device to prevent the elevator from moving again when the elevator car is stationary and the motor is in a state of power loss. In some forms of control, it brakes the elevator when the motor loses power.

Its control mode is generally to hold the brake loose when the power is obtained, and hold the brake tightly when the power is lost.

2. Motor: refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction.

The motor is represented by the letter M in the circuit (the old standard is D), its main role is to generate driving torque, as the power source of electrical appliances or various machinery, the generator is represented by the letter G in the circuit, and its main role is to use mechanical energy to convert into electrical energy.

Answer: Yes, under normal circumstances, the servo motor is connected to the relay.

Explanation: The function of the servo motor brake is to prevent accidental injury or equipment damage caused by inertial sliding by clamping the bearing or reducer through the brake holder when the motor stops running. Usually, the brake interface is set in the drive of the servo motor, and a relay is needed to realize the control of the brake.

Relay is an electrical control device, which realizes the switching control code system of the circuit through electromagnetic action, which can realize the control of high voltage and high current, and can also realize multi-channel control.

Expansion: In addition to relays, there are some other control devices that can also be used to control servo motors, such as PLC, touch screen, etc. At the same time, different models of servo motors and drives may also have slightly different brake interfaces, which need to be wired according to the specific product manual.

Hello dear, whether the servo motor has a brake or not can be distinguished in the following ways:1Distinguish by appearance:

The servo motor with brake is generally installed with a brake device on the shaft of the high stop motor, and it can be seen from the appearance whether there is a brake device. 2.Distinguished by technical parameters:

In the technical parameters of the servo motor, if there are parameters such as brake or brake torque, it means that the servo motor is with brakes. 3.Distinguish by the way of hunger wiring:

The servo motor with brakes needs to be connected to the brake power supply and brake signal line, and it can be judged whether it has brakes by checking the wiring.
