Floating Point Unit (FPU) Advantages

More robustNo scaling and saturation

Ease of use

Performance boostImprove calculation accuracy

Increase the code execution speed

Reduce the CPU bandwidth usage

Reduce the code size

C-code compiler friendlyCompatible with the C/Matlab simulation code


Fixed Point Development Dilemma

Simulation Platform

(i.e. C, Matlab)

Motor control development usually starts with simulation

in Floating Point

Floating Point Algorithm (C or C++)

Floating Point Unit

Can be easily ported to floating point device

(bi-direction)Fixed Point Algorithm

(C or C++)

Fixed Point Unit

Take time to convert the code to fixed point

>90% [20µs used for FOC]

Switching Frequency

Up to 20KHz

Communication USB connection: PC GUI interfaceTool: E10A for debug & development


H/W Key Points: Inverter & Control Board on the Same PCB

SH7216

H8S2212

3-phase inverter(6 x MOSFETs) 3 shunts

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)

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

E10A

Motor is a 3-phase Brushless AC motor also called PMAC (Permanent Magnet AC) without any sensors.

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.


PC Interface

All the starting parameters can be changed

Motor parameters can be modified

Current, speed PIs parameter can be changed

Everything in Real-time using the PC interface
