Abstract
A servomotor system is provided. The servomotor system includes an enclosure and a motor stator and rotor disposed in the enclosure. The servomotor system also includes a motor brake disposed in the enclosure and configured to selectively brake the rotor from rotation and a brake control switch disposed in the enclosure and coupled to the motor brake for selectively providing power to the motor brake for selectively engaging and/or disengaging the brake.

A servomotor system, comprising:
- an enclosure;
- a motor stator and rotor disposed in the enclosure;
- a motor brake disposed in the enclosure and configured to selectively brake the rotor from rotation;
- and
- a brake control switch disposed in the enclosure and coupled to the motor brake for selectively providing power to the motor brake for selectively engaging and/or disengaging the brake.

A servomotor system comprising:
- an enclosure;
- a motor stator and rotor disposed in the enclosure;
- a motor brake disposed in the enclosure and configured to selectively brake the rotor from rotation;
- a brake control switch disposed in the enclosure and coupled to the motor brake for selectively providing power to the motor brake for selectively engaging and/or disengaging the brake;
- an input/output circuit disposed in the enclosure and coupled to the brake control switch for applying control signals to the brake control switch, the brake control switch being configured to selectively engage and/or disengage the brake in response to the control signals;
- and
- circuitry external to the enclosure configured to apply brake signals to the input/output circuit for control of the brake.
4 more elements
A method of braking a rotor of a servomotor system, comprising:
- applying control signals to a brake control switch using an input/output circuit disposed within an enclosure of the servomotor system, wherein the enclosure houses a motor rotor and stator of the servomotor system;
- and
- selectively engaging and/or disengaging a motor brake disposed within the enclosure in response to the control signals.
