The TWR-MC-LV3PH is a low voltage, three phase motor control tower system module. This module uses the MC33937A three phase field effect transistor pre driver. This FET predriver designed for three phase motor control and similar applications. The three phase low voltage motor control board 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 three phase PMSM and BLDC motors. This tower module will operate off DC input voltages of 12V to 24V, 8A. The module contains reverse polarity protection circuitry. The TWR-MC-LV3PH is intended to be powered from an external power supply of 12V to 24V, 4A to 8A depending on the motor used. The module includes 5.0V and 3.3V supplies which are capable of providing power to the entire tower system.
