Overview
Even though most high voltage (110Vac/220Vac) 3-phase motor control applications are high power (>1kW) there are many applications that are low power (<500W). In those cases running on a high power system is not very efficient. To better demonstrate the capabilities in regards to efficiency in low power high voltage motor control we have developed this reference design (limited to 150W). This compact and cost-effective high voltage board is targeted to control various high voltage motors such as Brushless DC (BLDC) motors, Permanent Magnet Synchronous Motors (PMSM) and AC Induction Motors (ACIM) in sensored or sensorless operation.

The Leadshine (EL5-M0400-1-24) 400W 220VAC Brushless AC Servo Motor is designed for high-torque industrial applications. A 2,500-line incremental encoder is attached for servo positioning. The rated speed is 3,000 RPM and the peak speed is 4,000 RPM. The rated torque is 1.27 Nm and the peak torque is 3.82Nm. It responds quickly and moves quietly and smoothly with high precision for control systems. Cables are included. This motor has been tested with Microchip's high-voltage dsPIC motor control application notes and motorBench(R) Development Suite using MCHV-2 (DM330023-2) and MCHV-3 (DM330023-3).
