Motor control, phase current sensing, throttle/pedal sensing and complete vehicle power solutions for e-bikes, electric motorcycles and electric tricycles.

E-Two-Wheelers & E-Tricycles

Two- and three-wheeled electric vehicles sell in large volumes and are cost sensitive, yet must stay reliable through rain, water immersion and long-term vibration. RJMICRO uses linear Hall current sensors for the phase-current loop of hub and mid-drive motors, Hall switches and latches for throttle, cadence and speed sensing, and wide-input LDOs for the vehicle control supply.

Systems and scenarios covered

Electric drive systems

  • Hub motors and mid-drive motors: phase current sensing and commutation
  • controller over-current and stall protection

Vehicle electrical systems

  • Throttle and cadence position sensing
  • vehicle and wheel speed sensing
  • BMS bus current sensing
  • instrument and lighting supply
