Microchip dsPIC33CK32MP105 | Demoboard HIGH-PERFORMANCE E-SCOOTER BLDC MOTOR DRIVER
High-Performance E-Scooter BLDC Motor Driver Reference Design
Overview
| Topology | Motor Drive |
| Input voltage | 18-42 V |
| Output 1 | 42 V / 30 A |
Description
The High-Performance E-Scooter BLDC Motor Driver Reference Design is a high-performance BLDC/PMSM motor driver board used to demonstrate the capabilities offered by the dsPIC33CK high performance Digital Signal Controller (DSC) in conjunction with the MIC4104 (MOSFET gate driver) for motor control applications like E-scooters and E-bikes. The board is developed to meet the stringentdemands of modern motor control applications: high efficiency, compact dimensions,low cost, and high performance.
Features
- 18V to 42V VBUS Input Voltage Range (cover up to 10S batteries setup)
- Maximum output power: 350W
- 15A RMS (continuous) and up to 27A RMS (for short time) motor phase current
- Low-side shunt resistors on each inverter phase for current measurement (2 mΩ)
- PWM switching frequency range 8 kHz-50 kHz (typical 20 kHz)
- On board bias generator based on the MCP16331 buck regulator
- Six N-Channel MOSFETs with low RDS(on) (typical 1.9 mΩ)
- Faston Tab connectors for motor phases
- XT30 - type connector for convenient connection with the battery packs
- Support for sensored/sensorless motor control algorithms
- PICkit™ debugger/programmer interface
- Support for on board temperature measurement (NTC Thermistor)
- Auxiliar connectors (for custom functions like I2C, UART, THROTTLE
Typical applications
- Battery Chargers
- Digital Lighting
- AC to AC Converters, DC to DC Converters, AC and DC Motors:BLDC,PMSM,ACIM,SRM,etc, Inverters,Power Factor Correction.(PFC)
