The announcement comes at a time when electric motors are proliferating across a growing range of system applications and, as a result, developers need products and tools that ensure systems run as efficiently as possible while reducing board size, component count and energy consumption.
“New products like Microchip’s dsPIC33C DSC devices with their high analogue 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,” explained Joe Thomsen, vice president of Microchip’s MCU16 business unit. “Our enhanced support ecosystem helps engineers get their designs done faster with the optimum combination of performance, efficiency and reliability.”
Microchip’s motor control family additions include:
dsPIC DSCs: The functional safety-ready dsPIC33CK64MC10x DSCs for Field Oriented Control (FOC) are supported by motor control Plug-in Modules (PIMs) for existing motor control development boards and also with a new cost-effective low-voltage motor control development board. The MPLAB X Integrated Development Environment (IDE) and MPLAB Code Configurator (MCC) support rapid code development while the motor Bench Development Suite provides FOC motor control optimised code generation.
PIC32MK MCJ and MCM MCUs for FOC: The second-generation 32-bit MCU devices offer 32-bit floating point and DSP performance with flexible communications options. By sharing analogue features with the dsPIC33CK, they support seamless migration across device classes. These devices also feature 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 via 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: Provides a platform for application development and a reference for customer board design for the dsPIC33CK family.
Low-cost, high-efficiency refrigerator compressor reference design: Joins a growing family of turnkey designs that showcase best practices for application-specific motor control designs that shorten the time to market.
