A corresponding ecosystem of assist instruments will assist simplify motor management system growth and speed up time to market
To implement environment friendly, real-time embedded motor management programs in space-constrained functions, Microchip Expertise has launched a brand new household of dsPIC Digital Sign Controller (DSC)-based built-in motor drivers. These gadgets incorporate a dsPIC33 digital sign controller (DSC), a three-phase MOSFET gate driver and an non-compulsory LIN or CAN FD transceiver into one bundle. A big advantage of this integration is discount in part depend of the motor management system design, smaller printed circuit board (PCB) dimensions and decreased complexity. The gadgets are supported by growth boards, reference designs, utility notes and Microchip’s field-oriented management (FOC) software program growth suite, motorBench Growth Suite V2.45.
“Automotive, client and industrial designs are evolving and require greater efficiency and decreased footprints. These expectations usually come at a better expense and enhance in dimensional measurement,” stated Joe Thomsen, vp of Microchip’s digital sign controllers enterprise unit. “By integrating a number of system capabilities into one chip, the dsPIC DSC-based built-in motor drivers can cut back system-level prices and board house.”
The built-in motor driver gadgets could be powered by a single energy provide as much as 29V (operation) and 40V (transient). An inner 3.3V low dropout (LDO) voltage regulator powers the dsPIC DSC, which eliminates the necessity for an exterior LDO to energy the system. Working between 70—100 MHz, the dsPIC DSC-based built-in motor drivers present excessive CPU efficiency and might assist environment friendly deployment of FOC and different superior motor management algorithms.
Growth Instruments
An in depth ecosystem of motor management software program and {hardware} growth instruments helps make the design course of sooner and simpler, decreasing the shopper’s time to market.
The dsPIC33CK Motor Management Starter Package (MCSK) and the MCLV-48V-300W are two new dsPIC33-based built-in motor driver growth boards that present fast prototyping options with versatile management choices. The MCSK features a dsPIC33CK low-voltage motor management growth board, a 24V three-phase BLDC motor, an AC/DC adapter, a USB cable and different equipment. This cost-effective package helps quick prototyping of motor management functions that function between 12 and 48 VDC with as much as 10 Amps of steady present. The MCLV-48V-300W growth board allows quick prototyping of three-phase everlasting magnet synchronous motors which might be rated between 12 and 48 VDC and able to delivering as much as 25A RMS steady present per part. This inverter board introduces a brand new modular idea the place a separate dual-in-line module (DIM) is inserted into the board to configure it for a specific dsPIC DSC or MCU.
The motorBench Growth Suite is a free GUI-based software program growth device for FOC that precisely measures crucial motor parameters, routinely tunes suggestions management positive aspects and generates supply code by using the motor management utility framework (MCAF). The newest model, v2.45, features a highly effective new function known as zero-speed/most torque (ZS/MT), which allows designers to get rid of Corridor or magnetic sensors whereas maximizing the torque output from the motor, from start-up and at low speeds. This function can be utilized in pumps, energy instruments, e-Mobility and plenty of different functions.
MPLAB Uncover now incorporates many dsPIC DSC-based MATLAB Simulink fashions supporting varied motor management algorithms and growth boards. Microchip additionally supplies free system blocks for Simulink that can be utilized to generate optimized code from fashions for dsPIC DSCs and different Microchip MCUs.
The rising variety of dsPIC DSC-based motor management reference designs now consists of an automotive cooling fan, low-voltage ceiling fan and a drone propeller controller. These reference designs shorten the time to market by offering a production-ready answer for varied motor management functions. Sometimes, the board design information embrace schematics and a BOM, a board person’s information and motor management supply code which might be accessible for obtain.
