Beschreibung
The "e-Bike Traction Motor Control" targets high-performance, low power and cost-effective motor controlapplications; for example, applications for e-mobility (e-bikes). The "e-Bike Traction Motor Control" can drive BLDC/PMSM motors of up to 1 kW peak power and up to 60A peak-to-peak phase currents. The input voltage range is between 18V and 63V, covering the applications powered from battery strings of up to 15S (Li-Ion cells).For maximum battery efficiency and lower noise, a Field-Oriented Control (FOC) algorithm is used to control the motor speed and torque. Two rotor position feedback options are available, including three 120° spaced Hall sensors on motors so equipped, or sensor less current feedback using up to three shunt resistors for motors without Hall sensors.
Eigenschaften
- +18V to +63V VBUS Input Voltage range (cover up to 15S batteries setup)
- Maximum output power: 1000W
- 130A peak-to-peak (for maximum 120 seconds) motor phase current
- Low-side shunt resistors on each inverter phase for current measurement (1 mΩ)
- PWM switching frequency range 8 kHz - 20 kHz (typical 16 kHz)
- Six N-Channel MOSFETs with low RDS(ON) (typical 1.4 mΩ)
- XT30 - type connector for convenient connection with the battery packs
- Support for Field-Oriented Control (FOC) with Hall sensors or with motor phase current shunt resistors
- PICkit™ debugger/programmer interface
- Support for on board temperature measurement (MPC9700)
- Auxiliary connectors (for custom functions like CAN, I2C, UART, THROTTLE (acceleration), programming/ debug, etc.)
