Reference design for high-performance brushless DC (BLDC) and PMSM motors, the small dimension and excessive energy supply of this motor controller make it appropriate to be used as an influence software.

Energy instruments are extraordinarily essential instruments for each DIYers {and professional} fabricators. They simplify and expedite the method of drilling, slicing, buffing, and many others. Microchip has launched a reference design for a high-performance motor with excessive present delivering capability to simplify designing energy instruments.

The reference design from Microchip is appropriate to be used as a motor driver for energy instruments. The primary characteristic of this design is that it may be used for each the PMSM motor and BLDC motor of as much as 800W. The reference design can enable engineers to design compact, cost-effective, high-efficiency, and higher-performance designs. The reference design options the dsPIC33CK high-performance Digital Sign Controller (DSC) along side the half-bridge MOSFET driver for management purposes.

The motor driver can take enter from 12V to 28V VBUS Enter Voltage vary (covers as much as 6S battery setup) and presents a most energy of 800W. It could possibly present a excessive present of 15A RMS (steady) and as much as 50A RMS (for brief time) motor section present. The reference design includes a low-side shunt resistor on every inverter section for present measurement (1 mΩ) and has a PWM switching frequency vary of 12 kHz-50 kHz (usually 20 kHz). The design options six-N channel MOSFETs with low RDS(on) which allows smoother operations. The reference design can work with each sensored and sensorless motor design because it presents helps for sensored/sensorless motor management algorithms.

This reference design has been examined by Microchip. The corporate has additionally offered further assets resembling schematics, Gerber recordsdata, and many others. Yow will discover further knowledge in regards to the reference design on the corporate’s web site. To learn extra about this reference design click on here.
