Silent Sine Drive

The Arc200 features sinusoidal motor control so you can ride, skate, or bike without the annoying 10 - 16 khz screech in your ear.

Additionally the Arc200 offers reduced torque ripple, smooth motion, and more precise motor control.

Simple Setup

Setting up the drive is straightforward. Select your control mode (torque, velocity, voltage), configure your control input, then hang on for your test ride.

Reporting & Diagnostics

The Arc200 logs key data and users can review using the windows app. The drive provides a 5V power source for receivers, controllers, and features an API to allow even more advanced integrations.

Real World Reliability

We use waterproof latching connectors on the signal inputs, XT 90 for the power input, and 8mm bullet connectors for the phase wires.

The team at Freefly is testing the Arc200 to the limits on a daily basis in skateboards, bikes, and our infamous super scooter.

Specifications

  • Input Voltage: 4S (13.6v) - 12S (50.4v)*
  • Max peak phase current: 200A
    • Continuous current with little to no heatsinking (hot-side facing upwards and unobstructed): 60A
    • Continuous current when bolted to a typical EV aluminum chassis: 100-150A
    • Continuous current with infinite aluminum heatsink or water cooling, and forced air cooling on phase wires: 200A
  • Control Inputs: PWM, Analog (1x combined throttle/brake or independent throttle and brake), UART/CAN (for advanced users to interface through the Freefly API's QX protocol)
  • DC-Input: XT90
  • Phase-Output: 8mm Female Bullet

* (motor inductance must be above 12uH when operating over 6S battery voltage or damage may occur and warranty void!)

  • Sensor support: Fully sensorless, digital hall sensors, PWM
  • Operating modes: Torque mode (EV), speed mode (Multirotor, requires advanced user tuning), angle/servo mode (experimental, requires advanced user tuning and high-resolution motor encoder)
  • 23.4kHz switching frequency for zero audible PWM noise
  • Integrated 5A 5V BEC (Recommended continuous-current draw to be kept less than 3A)
  • Water resistant and splash proof - integrate into your application to avoid continuous water exposure
