Freescale Semiconductor Tower System Low-Voltage, Three-Phase Motor Control Module TWR-MC-LV3PH TWR-MC-LV3PH 信息指南

The 3-phase Low Voltage Motor Control board (TWR-MC-
LV3PH) is a peripheral Tower System Module. With one of
the available MCU tower modules accommodating a selected
microcontroller it provides a ready-made, software-
development platform for one-third horsepower off-line
motors. Feedback signals are provided that allow a variety of
algorithms to control 3-phase PMSM and BLDC motors.

The TWR-MC-LV3PH module features:

• Power supply voltage input 12-24 VDC, extended up to

• Output current up to 8 amperes (A)
• Power supply reverse polarity protection circuitry
• 3-phase bridge inverter (6-MOSFET’s)
• 3-phase MOSFET gate driver with over current and

under voltage protection

• 3-phase and DC bus-current-sensing shunts
• DC bus-voltage sensing
• 3-phase back-EMF voltage sensing circuitry
• Low-voltage on-board power supplies
• Encoder/Hall sensor sensing circuitry
• Motor power and signal connectors
• User LED, power-on LED, and 6 PWM LED diodes
