Electric motor clamping system

摘要

An electric motor system having a power supply, an electric motor connected to the power supply, an object driven by the motor having a range of motion and a substantially neutral position within the range of motion, a power sensor configured to sense power from the power supply, a position sensor configured to sense position of the object in at least a portion of the range of motion, an energy storage, a controller connected to the power supply and the energy storage, wherein the controller is configured to brake the motor as a function of the position sensor, the neutral position and the power sensor.

1. An electric motor system comprising:
a power supply; an electric motor connected to said power supply and having a braking element; an object mechanically coupled to said electric motor and driven by said motor; said object having a range of motion and a substantially neutral position within said range of motion; a power sensor configured to sense power from said power supply; a position sensor configured to sense position of said object in at least a portion of said range of motion; an energy storage connected to said electric motor; a controller connected to said position sensor, said power sensor and said energy storage; said controller configured and arranged to brake said motor using said braking element and power from said energy storage based on both said sensed position of said object by said position sensor relative to said neutral position and said sensed power from said power supply by said power sensor dropping below a threshold.
