The Torp TC500 2.X motor controller (inverter) is an aftermarket FOC controller designed for the Sur-Ron Light Bee e-moto and for TM25 electric motors. It supports 60–80 V nominal battery systems (22S), includes Bluetooth communication, and tunes through a Mobile App on iOS and Android.
This traction motor controller is built for high current e-motor use, and it combines power-focused limits with integrated protections. The TC500 2.X is rated for up to 350 A battery current* and up to 500 A phase current, while keeping inverter efficiency listed up to 99%.
The controller supports both sensored control with a HALL Encoder and sensorless control. It also supports communication with the original BMS (battery management system), plus multiple regenerative braking modes and multiple throttle modes.
Benefits
- FOC control (field oriented control) manages the traction motor using a dedicated FOC algorithm.
- 60–80 V nominal (22S) support fits common e-moto battery setups, with fully charged voltage up to 92.4 V.
- High current capability includes up to 350 A max battery current* and 500 A max phase current.
- Efficiency up to 99% is specified for the inverter for reduced losses at load.
- Bluetooth communication enables setup and control through a phone connection.
- Pre-calibrated setup is stated as ready without extra calibration steps.
- Built-in protections include overcurrent, overvoltage, undervoltage, and overtemperature protection.
Who is this for
The Torp TC500 2.X is intended for the Sur-Ron Light Bee electric motorcycle as an aftermarket motor controller (motor controller / inverter) upgrade. It is also listed as compatible with the TM25 electric motor, which makes it suitable for builds that move beyond stock configurations.
This controller is aimed at riders who want app-based configuration on iOS or Android, need support for the stock SurRon display, and require communication with the original BMS. It also fits setups where selectable regenerative braking modes and throttle modes are part of the tuning plan.
