Commissioning a Motor for use with EPC motor drives operating ST Motor Control
OVERVIEW OF THE PROCESS
• Background
• Equipment needed
• Measuring the motor parameters
• Inputting the motor parameters into
Microchip’s motorBench® Development Suite
• Generating the control rmware:
– Compiling
– Build
– Flash
• Operating the motor drive system
CONTROLLER BOARD BACKGROUND
• Process is for EPC9147C Only (A), equipped with ST Nucleo
G431RB (B) (that uses STM32G431RB (C))
• ST Motor Control Workbench®
• EPC9147C (Provided with motor drive KIT’s)
– Pre-programmed with a sensor-less motor control
algorithm for a specic motor (Teknic_M-3411P-LN-08D)
Note: When unboxing, it works only with the Teknic motor
(D)
MOTOR CONTROL BACKGROUND
• For sensor-less motor control algorithms:
– Only the three motor terminals connect to the inverter board
– Depends on specic motor parameters (a model of the motor
is used for control)
• New motor parameters must be programmed before operating
a dierent motor

• Resistance
• Inductance
• Pole pairs
• Back EMF
