Step-Pak™ Stepping Motor Amplifiers


Step-Pak SPD-6B Driver
Step-Pak™ SPD-6B Bi-Polar Stepping Motor Driver Module

The Step-Pak™ SPD-6B Stepping Motor Driver is a high efficiency, high performance motor driver. The engineered bi-polar, bi-level design provides absolutely minimum motor and driver losses which result in cool running motors and drivers, enabling high density packaging of equipment. Low DC voltage is applied to the motor windings when the motor is positioned. High voltage is applied synchronously with motor steps for fast acceleration and high running torque. Most of the switching losses inherent in chopper type drives is eliminated resulting in cooler running motors. The bi-level motor drive produces very low levels of radiated electrical noise which is critical during scientific data collection. When the motor is held at position, no currents are interrupted, therefore there are no radiated electromagnetic fields to interfere with measurements.

Step-Pak SPD-32M Driver
Step-Pak™ SPD-32M Bi-Polar Mini-Stepping Motor Driver Module
The Step-Pak™ SPD-32M Stepping Motor Driver is bi-polar, low noise, chopper type driver with mini-stepping capability. The two-phase, bi-level design is highly efficient and promotes cool running of motors and drivers, enabling high density packaging of equipment. Motor windings are compared to preset values. When motor current reaches the preset value, it is turned off and starts decaying to a preset low value when it is turned on again. When the motor is held in position, some low level switching electrical noise is generated.
