5xx4AC Offline Torque/Velocity Amplifiers

The 5xx4 series is a compact, offline solution for velocity and torque control of brushless servomotors. 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. In velocity mode, various performance levels can be achieved by deriving velocity feedback from the encoder, Halls or motor back-emf. 5x34ac

503 Low Power Torque Amplifier for Brushless Motors

The 503 is a compact and cost effective amplifier for torque control of brushless motors. Commutation information is derived from Hall sensors. Loop gains and continuous/peak current limits are set by a component header that can be shipped pre-configured for optimal performance. No potentiometer adjustments are required.

7xx5AC Offline UV Torque Amplifier for Brushless Motors

The 7xx5 series is a compact, offline solution (no transformer required) for sinusoidal torque control of brushless servo motors. 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.

7225X Low Drift 1-2 Axes UV Torque Amplifier for Brushless Motors

The 7225X series is a temperature compensated, low-drift solution for applications requiring a low torque ripple. A 4kHz bandwidth current loop ensures high performance torque control. A 2-axis version is available for applications where panel space efficiency is critical. The amplifier accepts controller commutated current commands in the standard UV format. The 7225X family operates from a DC supply without the requirement for an isolation transformer. Carrier cancellation PWM modulation is employed for zero crossover distortion. Models: 7225X1, 7225X1-50, 7225X2

4xx Series Torque/Velocity Amplifiers

The 400 series are third-generation amplifiers for dc brush motors.  Models operate from +24 to +225 VDC unregulated power supplies, and output peak currents from 10 to 30 A.  Built using surface-mount technology, these amplifiers offer a full complement of features for servo motor control. All models take industry standard ±10 V control signals as input, and operate motors in three different modes: torque, velocity, and voltage feedback with IR compensation.

4xx2 Series Torque Amplifiers

"Z" versions of 4122 and 4212 models feature 50% modulation that delivers no zero-current deadband for applications that require fine motion around zero such as voice coil motors, laser focusing, and wire bonding. Built using surface-mount technology, these amplifiers offer plug and play operation in a very small package. All models take industry standard ±10 V control signals as input, and operate motors in torque mode, or velocity mode using analog brush tachometers.

High Power Amplifiers & Systems

Copley Controls' high power 4-quadrant, filtered output DC amplifiers operate at high switching frequency enabling L-C filters to be built into the amplifiers case. The result is a low noise PWM power amplifier with characteristics much like a linear amplifier, but without the linear's high dissipation and bulk. Copley amplifiers are available either as individual components, or as complete systems. The system product lines include the DC power supply, fully integrated into rack assemblies for single or multi-axis requirements.
