SPD-32M Product Page

The Step-Pak SPD-32M Stepping Motor Driver isia bi-polar, chopper type driver with ministepping 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 switching electrical noise is generated.
