36V/144W Field-Oriented Control (FOC) Controller for BLDC Motors

The RX13T 32-bit microcontroller (MCU) is perfect for optimized single motor control applications used to drive vector control/field-oriented control (FOC) of a permanent magnet synchronous motor (brushless DC motor). The RX13T features a best-in-class built-in floating point unit (FPU) at 32MHz and various built-in peripheral functions, making for a compact and low BOM cost single motor control board. This design demonstrates a standard DC input (24V) and utilizes the axial position sensor, allowing motor axle position feedback without HALL effect sensors.

System Benefits​:

• Shows a discrete integration of high voltage/current MOSFETs
• Features a rotational sensor, a highly integrated contactless sensing device
• Supports a wide range of motor capabilities, from 12V up to 36V, max 4A (144W) 
• Offers simple interfacing to external control hardware (ADC input, PWM input)
