Apparatus to provide motor backdrive resistance

摘要

Apparatus to provide motor backdrive resistance are described. An example apparatus described herein includes a brake to engage an output shaft of a motor. The example apparatus also includes a brake release arm operably coupled to the brake. A reaction arm is fixed relative to the brake release arm and operatively coupled to the motor. The reaction arm causes the brake to disengage the output shaft of the motor in response to a reaction torque of the motor.

1. An apparatus, comprising:
a brake to engage an output shaft of a motor; a brake release arm operatively engaged to the brake; a motor mount to support the motor and including a pivot about which the brake release arm rotates, the pivot being held in a fixed position relative to the motor mount; and a reaction arm extending from the motor, an orientation of the reaction arm to be fixed relative to an orientation of the brake release arm, and the reaction arm to be operatively coupled to the motor to cause the brake release arm to disengage the brake from the output shaft of the motor in response to a reaction torque of the motor.
