Calculation method of motor torque

Calculation method of motor torque

Answer:

The relation between power, speed and torque is not related to motor form. All the rotating machines are the same. The formula is P = T * n / 9550, P is power, unit KW, T is torque, unit N.m, n is RPM, unit RPM. Different types of motors have different output characteristics, and there is no way to do the exact equivalent, mainly for use.
The characteristic of dc motor is that the lower the speed, the greater the torque, and the variable frequency motor is constant torque at lower rated speed, so it cannot be equivalent. Only by analyzing the operating condition of the system, the condition of the constraint can be made correctly.
There is a formula for your problem: Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Power torque = 9550 * output power/output speed Torque = 9550 * output power/output speed P = T * n / 9550 The formulas The relationship between motor power, torque and speed Power = force * velocity
