5000 Stepper Motor Drive Series

Pacific Scientific 5000 Stepper Motor Drives

The Pacific Scientific 5630 Stepper Motor Drive is an electronics module designed to regulate the currents in a two-phase bipolar stepping motor based on step and direction inputs. It offers adjustable output currents ranging from 5.0 to 8.0 amps/phase RMS, with a default setting of 5.0 amps/phase RMS, and operates with a nominal 160-volt dc bus. Key features include a bipolar chopper drive with a 20 kHz frequency for precise motor current control, internal power supplies powered by a 115-volt ac input, and built-in shunt regulator circuitry to safeguard against voltage spikes during motor deceleration. This ensures reliable operation and protection of the drive under various conditions.

The Pacific Scientific 5345/5445 Microstep Indexer/Drive integrates a powerful bipolar chopper drive with a programmable indexer, known as Pacific Scientific StepperBASIC, for precise control of stepper motor motion. In full step mode, the drive delivers an output current of 5.0 Amps per phase (2.5 Amps per phase for the 5345 model), and in microstep mode, it provides 3.5 Amps per phase (1.75 Amps per phase for the 5345 model), ensuring versatile and efficient operation tailored to specific application needs.
