Hardware description of EVAL-M3-102T

This chapter covers hardware design of the EVAL-M3-102T in more details. To enable users to make the EVAL-

M3-102T evaluation board a basis for a new development or modification of their own systems, all necessary

technical data like schematics, layout and components are also included in this chapter.

5.1

Motor Current feedback circuitry

5.1.1

Motor Shunt configuration

Both single shunt and leg shunt topologies are supported by the EVAL-M3-102T control board. The user needs

to make sure that the shunt configuration matches with power board hardware configuration. Please refer to

the power board User Manual for details. The shunt configuration can be changed in MCEWizard by clicking and

selecting in the pull down list marked with red box as shown in Figure 11.

Figure 11 Shunt Configuration

5.1.2

Motor External Current feedback configuration and calculation

The shunt resistance Rsh value can be found in the schematics or User Manual for the power board (For

example, the leg shunt resistors are 30mΩ for EVAL-M3-CM615PN and 100mΩ for EVAL-M3-TS6-606).
