Medium Voltage Digital Motor Control Kit for Stellaris®
Microcontrollers (DK-LM3S-DRV8312)
The Medium Voltage Digital Motor Control (DMC) kit (DK-LM3S-DRV8312), shown in
Figure 1, provides a great way to learn and experiment with digital control of medium
voltage brushless motors to increase efficiency of operation. This document describes the
DRV8312 hardware, and explains the functions and locations of jumpers and connectors
present on the board.
Figure 1. DK-LM3S-DRV8312 Kit (Stellaris® Version)
This EVM is meant to be operated in a lab environment only and is not considered by
Texas Instruments to be a finished end-product fit for general consumer use
This EVM must be used only by qualified engineers and technicians familiar with risks
associated with handling high-voltage electrical and mechanical components, systems,
and subsystems.
This equipment may be operated at voltages and currents that can result in electrical shock, fire
hazard and/or personal injury if not properly handled or applied. Equipment must be used with
necessary caution and appropriate safeguards employed to avoid personal injury or property damage.
It is the user's responsibility to confirm that the voltages and isolation requirements are identified and
understood, prior to powering the board and or simulation. If powered with a supply other than the one
included in the kit, do not touch the EVM or components connected to the EVM.
