Introduction
The IRMCS3012 reference design platform supports development of dual motor drive applications in the 1200W 1800W power range using the IRMCF312 digital control IC and the IRAMX16UP60A and the IRAM336-025SB IRAM power modules. The design kit includes two permanent magnet synchronous motor, a drive control board, a PFC inductor and the motor control development tools. The inclusion of motors allows immediate use of the kit, while the motor control commissioning tools support rapid evaluation of the drive board running the target motor.
