DC Motor Driver Simple Type: Amplifier
Models 4122CE and 4212CE are thirdgeneration amplifiers for dc brush motors from Copley Controls Corp. Built using surface-mount technology, these amplifiers offer plug and play operation in a very small package. All models take industry standard ±10V control signals as input, and operate motors in torque mode, or velocity mode using analog brush tachometers. Velocity loops using brush-tachometer feedback are used for open-loop speed controls, or in position control loops requiring improved regulation at low speeds.
