Freedom FRDM-MC-LVPMSM Development
Platform User’s Guide
1. Introduction
The Freedom development platform is a set of software
and hardware tools for evaluation and development. It is
ideal for rapid prototyping of microcontroller-based
applications.
The FRDM-MC-LVPMSM low-voltage evaluation
board, in a shield form factor, effectively turns a
Freedom development platform into a complete motor
control reference design, compatible with existing
Freedom development platforms, FRDM-KV31F and
FRDM-KV10Z, and the low cost motor FRDM-MCLVMTR.
The FRDM-MC-LVPMSM shield board implements a 3phase Permanent Magnet Synchronous Motor (PMSM)
interface platform that adds Field Oriented Control
(FOC) motor control capabilities, such as rotational or
linear motion, to your design applications.

FRDM-MC-LVPMSM Hardware Overview
2. FRDM-MC-LVPMSM Hardware Overview
The features of the FRDM-MC-LVPMSM hardware are as follows:
Power Supply Input voltage DC: 24-48VDC, via 5.5x2.1mm barrel connector.
Output current up to 5 amps RMS.
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.
Analog sensing (DC bus voltage, DC bus current, 3-phase back-EMF voltage).
5.5 VDC auxiliary power supply providing FRDM MCU board supplying.
Motor speed/position sensors interface (Encoder, Hall).
Freedom motor control headers compatible with Arduino™ R3 pin layout.
The FRDM-MC-LVPMSM board does not require any hardware configuration or jumpers setting. It
contains no jumpers.
