Motor-Control Processor Family Comes With Free Sensorless-Control Algorithm
With a selection of dsPIC® processors
optimised for motor control, and new,
free source code for sensorless Field-Oriented Control (FOC), Microchip
equips engineers to accelerate design
of advanced, energy-saving products.
The low-cost dsPIC33FJ12MC family includes
dedicated motor-control hardware including an
optimised ADC and a quadrature-encoder
interface. The on-chip PWM module provided has
two independent clock sources, enabling motor-control
and power-factor-correction algorithms to
be co-hosted on the same device.
The peripheral-pin select capability common to
all family members allows re-mapping of digital
I/O to target the smallest suitable device. Several
package options, including a 6mm x 6mm 28-pin
QFN, enable designers to minimise PCB space and
optimise board layout to reduce noise.
Microchip’s sensorless FOC algorithm enables
faster design of variable-speed controls for
Permanent-Magnet Synchronous Motors (PMSM),
and includes amotor start-up sub-routine as well
as phase-advance capability. The algorithm can be
fully evaluated using the dsPICDEM™ MC1 Motor
Control Development Board along with the
dsPICDEMMC1H Three-Phase High-Voltage Power
Module.
