Copley Model 7xx5AC

7xx5ACOffline UV Torque Amplifiers

For low torque ripple and smooth quiet operation, sinusoidal commutation is the technology of choice. The 7xx5 series is a compact, offline solution for sinusoidal torque control of brushless servomotors. Designed to interface to controllers, which generate a commutated current command, the 7xx5 accepts +/-10V commands for the U and V motor windings and internally synthesizes the W winding current.

A 3 kHz bandwidth current loop ensures high performance torque control. Carrier cancellation modulation is employed for zero crossover distortion. For noise sensitive environments, an optional internal edge filter is available to minimize PWM switching noise.
