“New products like Microchip’s dsPIC33C DSC devices with their high analog integration demonstrate our continued investment in simplifying motor control system design while reducing development and bill of materials costs in automotive, industrial, medical and consumer applications,” said Joe Thomsen, vice president of Microchip’s MCU16 business unit. “Our newly enhanced support ecosystem helps engineers get their designs done faster with the optimum combination of performance, efficiency and reliability.”

Microchip’s new motor control family offerings include:

• dsPIC DSCs: Cost-efficient, functional safety-ready dsPIC33CK64MC10x DSCs for Field Oriented Control (FOC). The new DSCs are supported by motor control Plug-in Modules (PIMs) for existing motor control development boards and a new low-voltage motor control development board. MPLAB X IDE and MPLAB Code Configurator (MCC) support quick code development and motorBench Development Suite provides FOC motor control optimized code generation.

• PIC32MK MCJ and MCM MCUs for FOC: Second-generation 32-bit MCU devices that provide 32-bit floating point and DSP performance and offer flexible communications options. The devices share analog features with the dsPIC33CK. They also offer multiple CAN-FD and USB ports. The MCUs are supported in the MPLAB X IDE with three development hardware options. Software support for the PIC32MK includes a suite of motor control software for sensored and sensorless applications through the MPLAB Harmony v3 Software Framework.

• motorBench development suite: Version 2.35 of Microchip’s GUI-based software development tool shortens the time required to spin a motor using FOC and generates optimized source code customized for a given motor. This release expands dsPIC33CK family support, adds a new Angle Track-Phase Locked Loop (AT-PLL) estimator, Field Weakening (FW), Maximum Torque Per Amp (MTPA), Dead-Time Compensation (DTC) and many other new features.

• Zero Speed/Maximum Torque (ZS/MT) algorithm: Eliminates hall sensors in applications demanding high torque at standstill or low speeds for low-inductance motors. Support is provided for the dsPIC33 DSCs, SAM and PIC32MK motor control MCUs.

• dsPIC33CK Low-voltage motor control development board:
