Servo motors generally refer to various motor systems with encoder structures that can perform motion state feedback.

When we select the type of servo motor, we are most concerned about the speed, torque and displacement accuracy of the motor. Of course, the reliability and stability of the motor is also very important.

The larger the torque of the motor, the stronger the power of the motor, so what is the torque related to?

The answer is the power and speed of the motor, the formula is T=9550P/n.

• T is the torque of the motor, the unit is Nm (NM),
• P is the output power, the unit is KW
• n is the motor speed, the unit is r/min (how many turns per minute)

It can be seen that when the power is constant, the motor speed is inversely proportional to the torque, and the higher the speed, the smaller the torque. If the speed of the motor is constant, the greater the power of the motor, the greater the torque of the motor.

Of course, a motor with greater power also has a larger volume and weight, requires more materials, and costs more. We should choose the most suitable motor according to actual needs, rather than causing waste.
