A few months back, we talked about the benefits of the electrification of motors in vehicles. Having the right silicon solution available is obviously the key element of the equation, but when software development for motor control for PMSM (permanent magnet synchronous motor) or BLDC (brushless DC) motors starts, the trouble really begins ... It usually takes a developer weeks or even months to implement a stable and optimized PMSM or BLDC motor control solution. And time is money.
Help is on it’s way. Freescale has recently introduced a series of fully loaded motor control development kits, offering developers one of the most integrated automotive motor control solutions on the market today. At the initial stage, seven development kits for Freescale’s Qorivva 32-bit microcontrollers are available to help reduce the time needed to develop motor control applications such as HVAC blowers, electric power steering, engine cooling fans, fuel, water and oil pumps and wipers. Freescale also plans to extend the series over the course of the next 12 months by including more Qorivva kits as well as kits based on the 16-bit S12 based MagniV mixed-signal product lines.
The initial kits feature controller boards powered by the latest Qorivva 32-bit MCUs such as MPC560xP, MPC564xL and MPC560xB families and a 3-phase low-voltage power stage board with the MC33937A FET pre-driver. These come to the developer with complete board schematics, user guides and development kit application notes. Integral to the kits is the source code of the motor control application software, based on the Automotive Math and Motor Control Library Set (MCLib). The kit is complemented by the FreeMASTER application visualization and control tool which allows tuning, debugging and building demos.
As an example, the image shows the 3-phase sensorless BLDC Development Kit with the Qorivva MPC5643L MCU.
