Drives
With technology enhancements and field experience, Compumotor offers the OEM750 Series, a compact microstepping drive that provides big performance in a small package.

Electronic Damping
All step motors are subject to mid-range instability, also referred to as parametric oscillations. Several problems are associated with these oscillations. They can cause the motor to stall, and thus cause the user to include a margin (typically at least 50%) of extra torque to overcome the oscillation. The OEM750 Series incorporates a subset of the patented electronic damping circuitry developed by Compumotor. This feature suppresses these oscillations, allowing the torque formerly reserved for safety margin to be used to do useful work, thus taking advantage of the full capabilities of the step motor.
 Minimizes stall condition
 Increases usable torque
 Higher accelerations

Current Loop Adjustment
Since the OEM750 Series is capable of operating from 24 to 75 VDC, while operating motors with a wide range of winding inductances, Compumotor incorporated current loop gain techniques to optimize motor performance. The loop gain adjustment is designed to maximize your system’s (drive, motor,and voltage) performance. Control over the current loop gain allows customers to take advantage of the motor’s capable torque and reduces audible noise and excessive heating of the motor. This gives users more choices when selecting a motor and the opportunity to pick the best motor for their application.
 Optimizes motor performance
 Reduces audible noise
 Reduces motor heating

Packaging
The OEM750 Series combines ASIC and surface mount technologies to minimize the product’s footprint, minimize overall package size, and increase product reliability.

Reliability
At Compumotor, producing reliable, quality products is our number one priority. Our OEM750 Series is designed with highquality standards and manufactured with state-of-the-art equipment and production methods. Before any product reaches our customers, it must pass a rigorous set of hardware and software tests. Today, Compumotor uses Highly Accelerated Life Testing (HALT) to uncover the product’s vulnerabilities,in order to produce a robust and reliable product. JIT (Just-In-Time) manufacturing and DFM (Design-For-Manufacturability) methods lend themselves well in creating the necessary flexibility to readily accommodate your special needs.

Compact, Low-Cost
