What is the maximum power of a 10,000 rpm DC motor? 10

The ** of the DC governor is about one or two thousand yuan per unit, and the cheap one is one or two hundred yuan. The ** of DC governor is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, it is necessary to understand and compare in many aspects.

DC governor is a motor speed regulating device, including motor DC governor, pulse width DC governor, thyristor DC governor, etc., generally a modular DC motor governor, set power supply, control, drive circuit in one, using three-dimensional structure layout, control circuit using micro-power consumption components, with a photocoupler to achieve current and voltage isolation transformation, the proportion constant, integration constant and differential constant of the circuit are adjusted with a PID adapter. It has the characteristics of small size and light weight, and can be used alone or directly installed on the DC motor to form an integrated DC ...

When the motor is running at a certain speed, it can output a certain torque, the speed is multiplied by the torque, that is, the output power, when the resistance is less than the torque, the car accelerates; When the drag is equal to the torque, the car travels at a constant speed; When the drag is greater than the torque, the car will slow down. So at the highest speed, the maximum power is consumed.

The electric motor of an electric vehicle consumes the most power when starting and climbing hills, which is slower at this time.

When driving at high speed on flat roads, the rated speed of the motor does not increase indefinitely, and the output torque decreases (faster than when accelerating) and the power consumption is also reduced.

Kiss! Hello, happy to answer your <>

What is the three-phase AC motor with a pro-power of 500w and a speed of 720 as follows: The calculation formula of the electrical power of the three-phase electricity is: line voltage u * line current i * power factor cos [p = 3 line voltage u (380v) line current i power factor cos ] the total power of three-phase electrical appliances is equal to:

Summary. Hello, happy to answer this question for you. The same power DC motor has a torque of 3,000 rpm and 2,000 rpm.

Hello, happy to answer this question for you. The same power DC motor has a torque of 3,000 rpm and 2,000 rpm.

Pro-lift pro, 2,000 rpm torque is large, because according to the formula of power, we know that p=fv p: power loss, f: force, v: speed pin. So it is 2,000 rpm of torque.

Engine torque is the torque that the engine outputs from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, which reflects the load capacity of the car within a certain range. The external torque is called torque or external force moment, and the internal torque is called internal force moment or torsional residual moment.

You are very happy to serve you and give you the following answer: the torque of a motor at 2,000 rpm is greater than that of a motor with 3,000 rpm. Since the speed of the generator is inversely proportional to the torque, when the speed of the generator decreases, the torque increases.

The reason why this happens is that the greater the load on the motor, the greater the torque requirement for the motor, and the lower the speed, the greater the load on the motor, so the torque will increase. To solve this problem, we should first understand the characteristics of the generator to ensure that the torque and the dispersion speed of the generator can meet the working requirements of the equipment. Secondly, devices such as reducers can be used to reduce the speed of the generator to increase torque.

Finally, the load of the generator can be controlled to ensure that the speed and torque of the generator can meet the working requirements of the equipment.

<> 600w motor is rated at a maximum power of 600 watts. Power refers to the amount of work done by an object in a unit of time, that is, power is a durable physical quantity that describes how fast or slow the work is done. Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction.

The electromagnetic DC motor is composed of stator poles, Chang hood rotor, commutator, brushes, casings, bearings, etc., and the stator poles of electromagnetic DC motor are composed of iron core and excitation winding. According to the different excitation methods, it can be divided into series excitation DC motors, parallel excitation DC motors, separately excited DC motors and compound excitation DC motors. Due to the different excitation methods, the law of stator pole flux is also different.

The speed of the DC motor is not directly related to the power, but is related to the voltage and load torque (when the load torque is less than the maximum output torque, the load torque has no effect on the motor speed, when the load torque is greater than the maximum output torque of the motor, the motor will stall or reduce the speed). The rotational speed formula of a DC motor in electrical engineering is as follows:

DC motor speed n=u-(ir+l*di dt) k

where U is the armature voltage, I is the armature current, R is the resistance of the armature loop, is the excitation flux, and K is the induced electromotive force constant. As can be seen from the formula, there are three speed regulation methods for direct motors, which are u, r, and r.

Because the actual power of the motor is related to the load of the motor, the larger the load, the greater the current, which can be simply understood as the input power (UI) of the motor and the output power of the motor (the power of the motor to do work with the load) is equal, when the voltage is certain (if it is not adjusted by adjusting the speed by adjusting the U, the voltage is unchanged), the larger the load, the greater the current.

Therefore, it is not possible to determine the relationship between rotational speed and power, and in the case of rated current, rated voltage, and rated power (rated output torque), it is possible to replace u in the formula with p i.

The relationship between motor power and speed:

p=t×n/9550

where P is the rated power (kw), N is the rated speed (r), T is the rated torque (the speed of the motor is determined by the frequency of the power supply and the number of pole pairs of the motor itself, and there is no direct relationship with the power.)

The power of the motor refers to the ability of the motor to output mechanical energy to drive the mechanical load. The speed of an AC motor is determined by the frequency of the power supply and the number of pole pairs of the motor. Under the condition that the grid frequency in China is 50Hz, the more pole pairs of the motor, the slower the speed.

For example, when the frequency f is 50Hz and the number of poles is 2 (the number of poles is 4).

RPM n 60f r 60 50 2 1500rpm;

At pole pair r 4 (pole number 8). RPM n 750rpm

There is no necessary relationship between speed and power, and a 150W DC motor may be found in the 2000R min series.

At the same speed, the power output of the motor with high power is larger.
