Embedded World 2014: NXP looks to streamline motor control

Launched today at Embedded World, the microcontrollers are based on the ARM Cortex-M3 processor and come with motor control firmware, easy to use tuning tools and two new motor control solution kits. Two 12bit, 12channel, 2Ms/s A/D converters and an on-chip quadrature encoder interface (QEI) enable control of both sensored and sensorless motor combinations. Four on-chip comparators enable fast response over-current/voltage monitoring and protection; while four flexible SCTimer/PWM timers provide up to 28 PWM channels in a tightly coupled analogue and timing subsystem, with minimal load on the CPU. "Today, many industrial designers face the challenge of creating designs with different types of motors, both sensored and sensorless," said NXP's Ross Bannatyne. "The LPC1500 series accelerates time to market with optimised mcus, firmware, software development tools and easy to use solution kits for BLDC and PMSM motors."
