The low cost, miniature, brushless DC motor controller packs enormous power into a tiny electronics package. Designed to drive 48-Volt brushless DC motors up to 1400 watts, this miniature controller may be the smallest in its class. Small physical sizes make it possible to develop high torque and operating speeds when overall product size and weight are application limited.

Orchid Technologies combined cost-sensitive engineering with precision power electronics to craft an efficient, high-performing, three-phase power-output stage. Working closely with silicon vendors, Orchid carefully selected FET output stage devices while perfectly matching drive and sensing technology characteristics.

Orchid selected an ST7MC microcontroller as the brains of this brushless DC motor controller. The ST7MC's feature-rich complement of flash program store, static RAM, Eeprom, patented motor controller, timers, analog-to-digital conversion circuitry, and robust processor reliability controls make the ST7MC a perfect fit in the motor control marketplace. The ST7MC's patented motor control subsystem provides a highly cost-effective method to control many different types of brushless DC motors. Sensor and sensorless motors, 120- and 60-degree styles are all supported.
