Hi-Mod is the name of a series of NEMA 34 frame stepper motors with integrated ministepping bipolar chopper drives.

Hi-Mod is the name of a series of NEMA 34 frame stepper motors with integrated ministepping bipolar chopper drives.

Two versions are currently available, featuring operation from optically isolated step and direction signals or with programmable motion controller which offers eight inputs and three outputs and the ability to store up to 128 lines of motion control program.

A PC based utility is available to allow easy motion program development using serial link communications.

The drive electronics is housed in a metallic box mounted to the motor body, the single package giving easy wiring and mounting requirements.

A single DC supply in the range of 48-75V is required and the units will operate at up to 4000 steps/revolution.

An electronic resonance damping circuit reduces noise and vibrations at low speed and a high efficiency chopper circuit with MOSFET final stage output reduces heating effects.

Hi-Mod is available in three stack lengths giving a shaft output power of up to 250W from a component offering high reliability, good performance and great ease of use at competitive prices.
