Professor Motor PMTRHR Retro High Performance Motor – 46,500 RPM

The Professor Motor PMTRHR Retro High Performance Motor is a high-performance FK130SH motor engineered for serious slot car racing applications. Featuring powerful neodymium magnets, carbon motor brushes and a dynamically balanced armature, this motor delivers an impressive 46,500 RPM at 12 volts, with maximum torque rated at 270 gm-cm.

Designed for demanding performance applications, the PMTRHR features an extended rear motor shaft for easier lubrication and compatibility with a motor commutator cooler.

High-Performance FK130SH Design

The PMTRHR combines high rotational speed with substantial torque output. Its neodymium magnets and carbon brushes are complemented by a dynamically balanced construction, helping deliver consistent high-speed motor performance.

Extended Rear Shaft

A particularly useful feature is the extended rear motor shaft, which provides easier access for lubrication and allows the use of a commutator cooler. This is a valuable feature for racers looking to maintain and optimise their motor during demanding racing applications.

Electrical Requirements – Important

This motor is not compatible with standard home slot car racing power supplies. Its substantial current requirements mean that an appropriately rated commercial racing power supply and electrical system are essential. The motor draws approximately 15 amps at stall and 0.65 amps with no load.
