Integrated DC servo motor and controller

摘要

An integrated motion control device having a controller mated to a motor body with a set of rigid, electrically conductive signal pins. The motor is direct-current and preferably brushless, and has Hall sensors within the motor body and an encoder at a back end for precisely determining rotor position. Signals from the Hall sensors and encoder are fed to a microprocessor contained in the controller and including a PID filter for servo control of the motor. The controller contains an amplifier for driving the motor and a power supply for providing appropriate levels of DC power to various elements of the controller and motor. All electrical signals between the motor and controller are transmitted via the pins, eliminating wiring harnesses of the prior art and related signal noise and wiring problems. The motor body and controller are affixed with a few screws, allowing the controller to be removed from the motor while the motor remains connected to an application. Communication ports are provided at a rear of the controller for connection to a computer or peripheral devices, and can be used to daisy-chain and synchronize a number of interconnected motors and controllers.
