Will the torque of the motor exceed the rated torque when accelerating?

The selection of torque sensor needs to consider the output signal, manufacturing process, material, type, physical properties of the material, material crystal structure, type, protection level and other factors, such as metal, mixture, stainless steel, polymer, ceramic, etc.; The types include diffusion silicon pressure transmitter, low differential pressure transmitter, strain gauge pressure transmitter, etc.; The types include weighing, force measurement, temperature, etc. The ** of the torque sensor is about a few thousand yuan per unit, and the cheap one is one or two thousand yuan. Before you choose, it is recommended that you fully understand and compare the torque sensor, and you can consult Beijing Shitong Science and Technology Innovation Technology ****.

From the perspective of torque balance, the motor accelerates because the driving torque of the motor is greater than the load torque. Then, there are two possible reasons for the acceleration of the motor: 1. The load torque decreases, and the motor driving torque remains unchanged.

2. The load torque remains unchanged, and the motor drive torque increases. In the second case, and the motor is operating at the rated state, the torque will exceed the rated torque.

The rated torque given by the motor is the output torque in the rated state, in the case of an electric bike.

I don't know if the rated state is a stable and uniform state. I can only say that "the rated state is the state in which the motor can run for a long time without problems, and the overall operation effect is the best." ”

When the power is constant, the faster the speed, the lower the torque.

When the power is the same, the faster the rotational speed, the less torque.

The current torque t = Newton-meter), would like to change to 100 (Newton-meter). If the power remains the same, it will be changed to 100 revolutions per minute).

When using an electric motor, the torque is mainly affected by the armature current, and to increase the torque, it is necessary to increase the current. However, too much current can overheat the motor. The main thing is to adjust the duration of the current and the size of the current, so that the motor heats up within the allowable range.

Auto-decompression start:

The use of autotransformer multi-tap decompression, can not only adapt to the needs of different load starting, but also can get a larger starting torque, is a kind of decompression starting method often used to start a larger capacity motor. Its biggest advantage is that the starting torque is larger, when its winding tap is at 80%, the starting torque can reach 64% when starting directly. And the starting torque can be adjusted by tapping.

It is still widely used today.

1. Your current torque t = Newton meters), you want to change it to 100 (Newton meters).

2. There are two methods: first.

1. Change the frequency; Clause.

2. Change the number of pole pairs.

3. In the case of the same power, change it to 100, rpm per minute) 4. If the power is changed, the method is according to the second way.

This can only be achieved by passing through a reducer.

It can only be solved by increasing the voltage and increasing the speed! If you use a reducer, the torque will be lower, and the higher the speed of the motor, the greater the torque!

Summary. Hello dear, the motor adds a reducer, and the torque will change. Torque is a special moment that causes an object to turn.

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, it 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 torque.

Reducer torque calculation method: speed ratio = motor output speed reducer output speed ("Gear ratio"Also called"Gear ratio"Know the motor power and speed ratio and use coefficient, find the reducer torque as follows: reducer torque = 9550 motor power motor power input speed ratio use coefficient know the torque and reducer output speed and use coefficient, find the reducer required with the following formula for motor power:

Motor power = torque 9550 motor power input speed ratio use factor.

You are so pro, the motor adds a reducer, and the torque will change. Torque is the width of the moment that causes an object to turn. 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, it 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 torque. Reducer torque calculation method:

Gear ratio = motor output revolutions reducer output revolution ("Gear ratio"Also called"Gear ratio"Know the motor power and speed ratio and the use coefficient, find the reducer torque as follows: reducer torque = 9550 motor power motor power input speed ratio use coefficient know the torque and reducer output speed and use slag coefficient, find the reducer required with the motor power as follows: motor power = torque 9550 motor power input speed ratio use factor.

Torque is not torque.

If you are pro-change, you will get bigger.

Summary. Power = torque * speed, so double the torque and double the power. So 1000 220 is approximately equal to.

Power = torque * speed, so double the torque and double the power. So 1000 220 is approximately equal to.

What is 220.

Voltage. Power is equal to UI

Can you help me see what's wrong with this.

There are no problems and it can be operated.

I made my own brushless motor with my own test data.

I don't know if this motor has good torque.

You test a few more times, remove some cases, and take an average.

Thank you, you're welcome.

The maximum torque of the motor is one of the basic parameters of the motor, and it is also the most important parameter of the motor, and the common unit is Niu. m).
