Tamiya Sport-tuned vs. Torque-tuned motor

Decided to put together a quick reference for these two “modified” (slightly) 540-sized motors from Tamiya. RS540 Sport Tuned Motor features performance enhancements above stock silver can motors for faster acceleration and higher top speeds!

Tamiya 540 motor comparison

Standard 540
Turns: 27T
*Top speed: 24.3Km/h

Torque-Tuned Motor
Turns: 25T
*Top Speed: 26km/h

Sport-Tuned Motor
Turns: 23T
*Top Speed: 29.1km/h

*Measured using TT-01 chassis with kit-standard gear ratio.

(above pic)Tamiya has developed this new Torque-Tuned motor, which offers performance that is between that of a standard Type 540 motor and Item 53068 Sport-Tuned Motor. Compared to a standard Type 540 motor, it offers a higher top speed and improved acceleration when used with a RC car model’s standard gear ratios.

Actual can dimensions are 50mm long x 35.5mm diameter w/ 3mm shafting.

For reference, here’s the

Tamiya (#53696) Super Stock Motor TZ

• A high performance motor for electric radio control car use.
• A high torque motor is designed for endurance race or low speed track.
• Can be disassembled for maintenance. Features standard brushed.
• Blue anodized end bell with brush dampers.
• Features terminal heat sink and detachable chip capacitor.
  [Caution] The rotation direction of the motor is counter-clockwise when viewed from the gear end.

  Specification:

• No. of turn: 23 turns
• Proper voltage range: 7.2V
• RPM at no load: 26,500rpm (7.2V)
• Best efficiency: 78%
• Torque at best efficiency: 500gf.cm (7.2V)ROTATION DIRECTION
  make sure the rotation direction of the motor is correct. The rotation direction of the motor is counter-clockwise when viewed from the pinion gear end. Running the motor in the opposite direction will result in reduced performance.

  REPLACING BRUSHES

• Check brushes after use 10-15 full battery packs.
  

  CAUTION WITH RUNNING THE MOTOR

• Make sure to replace plastic bearings with ball bearings. Plastic bearings cannot endure motor rotation.
• Continuous running will damage the motor. Let the motor cool after each full battery run.
• Never overload the motor. Make sure that all the gears and rotating parts move smoothly to prevent motor burn out.
• Never cover the motor. Covering will hinder heat dissipation resulting in damage.
• If motor gets damaged or over-heats, performance will deteriorate.
• Periodically disassemble, clean and maintain motor after running it.
• Use only genuine Tamiya spare parts.
• Communtator Cleaning Brush Set (53486) is recommended for cleaning. Replace the brush on one side (+ or -) and run the motor without load.
