Abstract
The present invention provides a system for controlling the speed of a motor by altering the magnetic field of the motor. The system includes field modification module, and a motor having field windings and a rotor. The field windings are configured to receive a driving signal that generates a magnetic field causing a rotation of the rotor. The field modification module is proximate the motor and alters the magnetic field in response to an input signal thereby controlling the speed and torque of the rotor.
Claims23
A system for controlling the speed of a motor, the system comprising:
- a motor having a field winding configured to receive a driving signal and generate a magnetic field causing a rotation of a rotor based on the driving signal;
- a field modification module proximate with the motor and configured to alter the magnetic field in response to an input signal thereby controlling the speed and torque of the rotor.
A system for controlling the speed of a motor, the system comprising:
- a motor having a field winding configured to receive a driving signal and generate a magnetic field causing a rotation of a rotor based on the driving signal;
- a field modification module includes a coil external with the motor and configured to receive an input signal to generate a flux that modifies the magnetic field thereby controlling the speed and torque of the rotor.
