Solution specifications

▶ Vacuum cleaner reference design provides a complete three-phase motor control solution, reducing development time. Optional software includes sensorless back electromotive force (BEMF) with zero-crossing detection for maximum speed operation, and field-oriented control (FOC) for quieter operation, maximum torque and maximum energy efficiency.

▶ Compact shape, 55mm diameter round shape, can be installed on top of BLDC motor. This design uses the dsPIC33CDV64MC106 integrated motor driver with a dsPIC® DSC motor controller and three-phase MOSFET Driver to save board space and reduce component count.

The reference design specifications are as follows:

• dsPIC®DSC integrates a three-phase MOSFET Driver

• Support 400W output power (continuous): battery input voltage range: 12-28V; maximum phase current: 17A RMS (continuous)

• PWM frequency range: 8-65kHz

• Three-phase shunt motor phase current measurement

• Able to achieve mechanical speed >100k

• Integrated protection functions: over-current detection; input under-voltage and over-voltage detection; temperature detection
