The TM50 Series Motor Encoder PCB (replacement encoder PCB) is a direct replacement sensor board for TM50, TM50 Pro, and TM50 Speed motors. This internal motor PCB installs inside the motor and sends position feedback and speed feedback to the motor controller.
This part is used when a TM50 series motor needs the feedback signal path restored after the original encoder PCB fails or becomes damaged. The product is an encoder board (PCB) only, so it does not replace the motor controller and it does not replace the complete motor.
This encoder sensor board is specified as a TM50 series replacement part, which means it is intended as a like-for-like swap in TM50, TM50 Pro, and TM50 Speed motor repairs. The listed mass of this spare PCB is 0.1 kg.
Benefits
- TM50 series compatibility: specified for TM50, TM50 Pro, and TM50 Speed electric motors.
- Position feedback output: the sensor board provides position feedback signals to the motor controller.
- Speed feedback output: the encoder PCB also provides speed feedback signals for control.
- Direct replacement use: intended to replace a failed or physically damaged TM50 series encoder PCB.
- Internal motor electronics: this PCB mounts inside the motor, so it is not an external accessory.
- Correct part type: this is an encoder PCB (sensor board), not a motor controller (controller).
- Light spare part: the specified mass is 0.1 kg for the PCB as a replacement component.
Who is this for
This TM50 encoder board is for service work on specific mid-drive motor models in the TM50 series. The compatible motor models are listed by name as TM50, TM50 Pro, and TM50 Speed.
This replacement encoder PCB is selected when you are repairing the motor’s encoder or sensor electronics and need to swap the original board. This part is not intended to replace a motor controller or a complete motor assembly.

Why choose
This TM50 Series Motor Encoder PCB is defined as a dedicated replacement part for TM50 series motors, so its role is focused on restoring the motor feedback interface after a board failure. The board’s job is to transmit position and speed feedback to the controller, which is a different function than power control.
The product is an internal electronics spare part with a specified 0.1 kg mass, which helps identify it as the encoder PCB only. This makes it the correct choice when the motor runs but the encoder feedback circuit needs repair.
