Table 3) is primarily used for the Permanent Magnet Synchronous Motor (PMSM) sensorless application but you can also use it for the BLDC sensorless application. You can also adapt the application to other motors by defining and changing the motor- related parameters. -
Page 4: Tower System
Hardware setup Figure 2. MIGE motor 4.3. Tower System To run the BLDC application using the Tower System, these Tower boards are required: • Tower board with a Kinetis V series MCU (TWR-KV46F150M or TWR-KV58F220M). • Tower board with Kinetis E series MCU (TWR-KE18F). - Page 5 Tower System. The phase voltage and current feedback signals are provided. These signals enable a variety of algorithms to control the 3-phase PMSM and BLDC motors. A high level of board protection (over-current, under-voltage, over-temperature) is provided by the MC33937 pre-driver.

Figure 7. Assembled Tower System 4.5. Freedom development platform To run the BLDC application using Freedom, you need these Freedom boards: • Kinetis KV11Z Freedom board (see FRDM-KV11Z), Kinetis KV31F Freedom board (see FRDM-KV31F), Kinetis KE15Z, or Kinetis KE16Z Freedom board. - Page 10 Freedom development platform into a complete motor-control reference design compatible with the existing Freedom development platforms (FRDM-KV31F, FRDM-KV11Z, FRDM-KE15Z, and FRDM-KE16Z). The FRDM-MC-LVBLDC board does not require any hardware configuration or jumper settings. It contains no jumpers. Figure 8.

The FRDM-KV31F board hardware is form-factor compatible with the Arduino R3 pin layout, providing a broad range of expansion board options, including FRDM- MC-LVPMSM and FRDM-MC-LVBLDC for PMSM and BLDC motor control. The FRDM-KV31F platform features OpenSDA, the open-source hardware embedded serial and debug adapter running an open-source bootloader.

Remote operation is provided by the FreeMASTER software via the USB interface. FreeMASTER 3.0 is required for optimal operation of the application. The FreeMASTER 3.0 application installation is available for download at www.nxp.com/freemaster. Perform these steps to control a BLDC motor using FreeMASTER: 1. Open the FreeMASTER project file (bldc.pmp) in the <sdk_package_folder>middleware/motor_control/freemaster folder. - Page 18 Figure 15. FreeMASTER communication status when communication is established successfully 3. Control the BLDC motor using the control page.
