Claims

[Scope of utility model registration request]

Multiple frequency generators that detect the rotational speed are connected to the rotor shaft of the motor so that the same frequency output can be obtained for different rotational speeds, and this output is used as a speed feedback signal to control the motor. An electric motor with a frequency generator, characterized in that it returns to the device.
