DC Motor Torque: 95% Power to Stator, 5% to Motor?

In summary, in a conventional DC motor 95 percent of the power is supplied to the motor while only 5 percent of the power is supplied to the stator. However, if a motor has 95 percent power supplied to the stator and only 5 percent to the motor, it would not be very efficient and not economical to use.

In a conventional DC motor 95 percent of the power is supplied to the motor while only 5 percent of the power is supplied to the stator. consider the torque equation. what if you have a motor that has 95percent power supplied to the stator and 5 percent to the motor. the motor will still run but why do we not use this motor?

It sounds like you're referring to the motor efficiency. If the shaft output is only 5% then the motor is not very efficient. So it would not be economical to use it.

Related to DC Motor Torque: 95% Power to Stator, 5% to Motor?

1. What is the significance of having 95% power to the stator and only 5% to the motor?

This distribution of power is known as a "torque split", and it allows for more efficient operation of the DC motor. The stator is responsible for creating the magnetic field that drives the rotation of the motor, so by providing it with the majority of the power, it can perform its function more effectively.

2. How does this torque split affect the overall performance of the DC motor?

The 95% power to the stator ensures that the motor has enough torque to overcome any resistance or load, while the 5% power to the motor allows for precise speed control. This balance between torque and speed results in improved efficiency and performance of the motor.

3. Can the torque split be adjusted for different applications?

Yes, the torque split can be adjusted by changing the voltage or current supplied to the stator and the motor. This allows for customization of the motor's performance to suit specific needs and applications.

4. Are there any drawbacks to using a torque split in a DC motor?

One potential drawback is that the motor may experience some overheating due to the unequal distribution of power. This can be mitigated by proper design and cooling techniques.

5. How does the torque split in a DC motor compare to other types of motors?

The torque split in a DC motor is unique to this type of motor and is not found in other types such as AC motors. However, other types of motors may have similar methods of controlling torque and speed, such as variable frequency drives in AC motors.
