Hardware setting of the STEVAL-IHM023V2

Doc ID 15870 Rev 4

27/48

Table 5 shows jumper settings for a low-voltage BLDC motor in single-phase FOC current

control. Please confirm that the input voltage (mains voltage) of the demonstration board in

this case is in the range of 18 VDC to 35 VDC. If it is necessary to supply the motor with

a voltage lower than 18 VDC, please remove the W3 jumper and connect the auxiliary

voltage to the J3 connector.

In this configuration it may be necessary to modify R2, R4, and R7 resistors according to

applied supply voltage.

4.3

Hardware settings for FOC in three-shunt configuration

To drive any motor, the user must ensure that:

●

The motor control demonstration board is driven by a control board that provides the

six outputs signals required to drive the three-phase power stage

●

The motor is connected to the J4 motor output connector

●

If using an encoder or Hall sensor connection, it is connected to connector J5

●

If using a tachometer connection, it is connected to connector J6

●

If using the brake control feature, connect a dissipative power load to J7 connector
