The Motor-Expert software features accurate speed and current control loop functions. A diagnostics field within the software interface provides insight into inverter and motor operation. The interface also enables users to visualize system operation, displaying the status of data including current, speed, status, current error, and speed error. Motor tuning is performed through the Motor-Expert user interface with new control loop coefficients being updated in real time without having to recompile code.

It supports both sensor and sensorless operation, providing developers with additional system cost-reduction options and is transportable to many commonly embedded microcontrollers. Motor-Expert software supports the cost-effective single-phase motor architecture, slashing the number of high-voltage devices, associated costs, system complexity and inventory burden. BLDC motors are widely used in modern, high-efficiency appliances such as compressors, fans and water pumps in domestic appliances, and for ceiling fans and room air conditioning systems.īLDC motors frequently use three windings (phases) requiring six high-voltage IGBTs or MOSFETs to operate. Power Integrations released its Motor-Expert software, an embedded “C” code application, library and control GUI that enables designers using the company’s BridgeSwitch brushless DC (BLDC) motor driver ICs to precisely control and tune single-phase motors.
