Figure 2. TG Drives motor
The motor has two types of connectors (cables). The first cable has three wires and it is designated to
power the motor. The second cable has five wires and it is designated for the Hall sensors’ signal
sensing.
NOTE
For the sensorless control mode, you need only the power input wires. In
the position control mode, connect also the sensor wires to the NXP
Freedom power stage. The wiring is described in Section 2.4, “Hardware
assembling”.
2.4. Hardware assembling
1. Connect the NXP Freedom PMSM power stage and the MIMXRT1050-EVK board together by
wires according to the pin assignment (Table 3) and the interconnection diagram (Figure 3).
2. Connect the TG Drives motor 3-phase wires into the screw terminals (J7) on the NXP Freedom
PMSM power stage.
3. In case of the position motor control, connect also the five wires from the motor sensors to the
NXP Freedom PMSM power stage interface. The pins on the connector are:
1 — +5 V
2 — GND
3 — ENC A (Phase A)
4 — ENC B (Phase B)
5 — ENC I (Index)
4. Plug the USB cable from the USB host to the OpenSDA micro USB connector (J28) on the EVK
board.
5. Plug the 24 V DC power supply to the DC power connector on the NXP Freedom PMSM power
stage.
