Motor Control
Modular and Versatile Platform
The Servo Drive Reference Model (RM) combines Toshiba’s optimized motor
control MCUs with Toshiba’s low R
DS(ON)
Power MOSFETs providing high
efficient control and drive solutions for brushless DC (BLDC) motors. The
modular concept offers a high degree of flexibility for Field-Oriented Control
(FOC) and closed-loop positioning of up to three BLDC servo motors by a
single MCU resulting in reduced system cost. The RM gives a quick start for
developers to realize advanced servo motor systems.

Vector control of up to 3 BLDC
servo motors by a single MCU
Toshiba's Arm® Cortex®-M4F core-
based microcontroller is dedicated to
Field-Orientated motor control. The
built-in Vector Engine (VE) takes care
for the complex vector control
calculations and feeds the
Programmable Motor Drive (PMD)
block to generate the PWM waveforms
and perform other necessary functions
such as dead-time control.
Motor control firmware
The firmware API provides a simple
and straight forward interface to
configure and control the motor.
Beside speed, torque and position
control there are functions for current
measurement, over/under voltage
protection, or stall detection. All APIs
can be accessed from remote via a
command protocol.
200W power stage / 3-phase
inverter
The 3-phase inverter design is based
on the 100V / 150A TPW3R70APL low-
voltage MOSFET from the latest U-
MOS IX process technology which
provides industry leading
performance. With max. R
DS(ON)
of just
3.7mΩ, the drive, switching and output
charge losses are reduced significantly
enabling efficient driving of 48V BLDC
motors up to 200W.
