Product overview and role on track

The Yokomo YOKRPM-TC45 is presented as a hobby-grade brushless motor built for R/C car applications. It uses an M3 4.5-turn winding and this description addresses mounting considerations, installation pointers, and how that motor class influences setup decisions for club and track running.

Fitment requires checking your chassis motor mount pattern, the motor can length, shaft diameter, and pinion spacing. Verify that your electronic speed controller (ESC) can handle the motor's current draw and that your battery type and capacity suit the intended runs.

Installation notes: keep pinion and spur gear alignment precise to avoid early wear, fasten the motor with the correct screws for the mount, and confirm there is adequate clearance around cooling fans or bodywork. Pair the motor with an ESC whose timing and throttle profiles match a 4.5T characteristic to achieve the desired response.

Tuning role: a 4.5T unit typically balances torque and top speed for club-level competition. Tweak gearing, ESC punch settings, and tyre choice to improve traction and lap time consistency rather than seeking maximum top end.

Specifications

  • Item Yokomo RPM-TC45 - M3 Brushless Motor 4.5T
  • Model Number YOKRPM-TC45
  • Brand Yokomo
  • Compatibility R/C car applications, confirm motor mount and ESC match before installation
  • Notes 4.5T designation indicates winding turn count used for torque/RPM characteristics

Choose this motor when your setup and event regulations reward a mix of torque and controllable top speed, and always confirm both mechanical and electrical compatibility with your chassis and ESC.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does a 4.5T winding affect on-track behaviour?

A 4.5T winding typically trades some top speed for stronger, more usable torque and acceleration on club circuits. That makes it a practical choice when drivability and lap consistency matter more than outright top end.

What physical checks confirm this motor will fit my car?

Measure the motor can length, shaft diameter, and motor mount screw pattern, and check pinion spacing against your spur gear. These dimensions determine mechanical fit before you consider electrical compatibility.

Which ESC settings should I start with for a 4.5T?

Begin with conservative timing and mild throttle curves, then increase punch or timing gradually while monitoring motor temperature. Use short test runs to dial in acceleration without overheating the system.

What routine checks help prolong motor life?

Regularly inspect bearings for smooth rotation, remove debris from the can and vents, check pinion/spur mesh, and monitor temperatures during sessions to avoid thermal stress.
