H/W Key Points:
Inverter & Control Board on the Same PCB
 20 Renesas products used: 2 x MCUs, MOSFETs,
Comparators, Power on Reset, E²PROM, buffer, logic.
 Board is consuming low power: fully USB powered to
run the low voltage motor up to 6000 RPM (at 5V)
E10A
 Single PCB for control & inverter stages (6
transistors & 3 shunts on the back side)
 Two connectors only: one for the Motor & one for
the USB connector
SH7216
H8S2212
3-phase inverter
(6 x MOSFETs)
 Motor is a 3-phase Brushless AC motor also called
PMAC (Permanent Magnet AC) without any sensors.
3 shunts
 The SH7216 is driving the Motor in fully sensorless
mode using sinusoidal signals.
 The motor efficiency is maximal as the control
algorithm is fully field oriented controlled.
