Motor control operations
Environmental considerations
The kit is not electrically-isolated from the DC input. This topology is very common in motor
drives. The microprocessor is grounded by the integrated Ground of the DC bus. The
microprocessor and associated circuitry are hot and MUST be isolated from user controls
and serial interfaces.
An isolated DC power supply can be constructed using an isolation transformer and a
variable transformer. A schematic of this DC power supply is shown in the application note,
"AN438, TRIAC + Microcontroller: safety precautions for development tools" (although this
application note was written for TRIAC, the isolation constraints still apply for switching
semiconductor devices such as MOFSETs.)
Isolating the application rather than the oscilloscope is highly recommended in any case.
Hardware requirements
To set-up the STEVAL-IHM015V1 demonstration board system, the following items are
required.

The board itself: STEVAL-IHM015V1
An insulated DC power supply up to 24 V, 8 A
Softec’s inDART-STX (not included in the package)
Softec’s ICC isolation board (not included in the package)
Two 10-pin flat cables (not included in the package)
A brushless PM motor Ametek (not included in the package)
An insulated oscilloscope (as needed)
An insulated multimeter (as needed).
Warning:
Warning:
The STEVAL-IHM015V1 demonstration board must only be
used in a power laboratory. The voltage used in the drive
system presents a shock hazard.
Any measurement equipment must be isolated from the main
power supply before powering up the motor drive. To use an
oscilloscope with the kit, it is safer to isolate the DC supply
AND the oscilloscope. This prevents a shock occurring as a
result of touching any SINGLE point in the circuit, but does
NOT prevent shocks when touching two or more points in the
circuit.
