Effect of rotor winding turns on motor performance

The number of turns of the motor rotor winding has an important impact on the performance of the motor. The change in the number of turns directly affects the magnetic flux of the motor, which influences the performance parameters such as torque, speed and power of the motor.

1、Output torque

The more turns, the stronger the magnetic field strength inside the motor and the higher the output torque.

In your example, the number of turns of a double stranded 50-turn winding is actually the same as the number of turns of a single stranded 100-turn winding, so the output torque of both should theoretically be the same.

2. Speed and power

More turns will increase torque, but will decrease RPM.

Power is proportional to both torque and speed, so in the case of the same power, the number of turns will lead to a decrease in speed.

Because the number of turns is the same, so single strand 100 turns and double strand 50 turns of the speed is theoretically the same.

3、Rated voltage

Voltage is not directly related to the number of turns, but with the current and the impedance of the winding.

Theoretically, changing the voltage will not affect the number of turns on the motor performance.

If the voltage is changed, the number of turns may need to be readjusted in order to maintain the same motor performance.

4. Final Motor Output Effect

If the voltage is reduced from 10V to 5V, the output power and torque of the motor will be reduced accordingly.

The number of turns may need to be adjusted in order to maintain the same motor output performance.

If the number of turns remains the same, the voltage reduction will result in a decrease in current, affecting the output performance of the motor.
