Motor Control Module

The CMI-5015-12 Motor Control Module is specifically designed for operating both fractional and integral horsepower three-phase motors. The module delivers currents of 30 A, with peaks up to 40 A off a single 4- to 12-V power supply. It is packaged in a miniature, hermetically sealed module, making it ideally suited for high-performance battery-operated three-phase Brushless Motor Control applications, such as robotics, electromechanical valve assemblies, battery-operated motors, positioning systems, fans, and blower motors. The module is ideally suited for harsh environments where shock, vibration, and extreme temperature are present, and operates over the full military temperature range of –55ýC to 125ýC.

The CMI-50I5-12, plug and play module contains the latest ASIC technology for commutation, cross conduction protection, braking, under voltage lock out protection, temperature compensated reference, and cycle-by-cycle current limiting. Its high-efficient power stage is made up of high and low side drivers for driving the gates of low resistance N Channel power MOSFETS.

Coupled with a unique low loss current sensing circuit and internal bus capacitors, the need for large external components is eliminated. The CMI-5015-12 is designed with 60ý electrical sensor phasing, but a 120ý factory option is available. An internal DC/DC converter provides logic voltages allowing the module to operate off a single supply as low as 4 V while supplying maximum current to the output stage.

The CMI-50I5-12 sells for $375 per 1000.
