Company further simplifies system development with
products, tools, a torque-maximizing algorithm and additions to industry’s
broadest offering of motor control reference designs
As electric motors proliferate across a growing
range of system applications, developers need products and tools that ensure
systems run as efficiently as possible while reducing board size, component
count and energy consumption. Microchip Technology Inc. (Nasdaq: MCHP) today
announced it has expanded its motor control offering with
digital signal controllers (DSCs) and microcontrollers (MCUs) that are
supported by design tools, development hardware, a torque-maximizing algorithm
and a refrigerator compressor reference design.
“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 motor control family additions include:
·
dsPIC® DSCs:
The cost-optimized, functional safety-ready dsPIC33CK64MC10x DSCs for Field
Oriented Control (FOC) motor control 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. MPLAB® X Integrated Development Environment
(IDE) and MCC support rapid code development while motorBench® Development
Suite provides FOC motor control optimized code generation.
·
PIC32MK MCJ
and MCM MCUs for FOC motor control: The second-generation 32-bit MCU devices
offer 32-bit floating point and DSP performance with flexible communications
options. By sharing analog 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
Integrated Development Environment (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.
