Mars RB370 Brushed Motor


Availability: In stock

The Mars RB370 is our take on the standard 370 class of motor, and we see it as the RB180’s gym-going cousin, meaning it has been developed with the same goal of striking the balance between performance, reliability and price. Steadfast power is the RB370’s game. In numbers, that means a nippy 25,000 RPM at 12V and a stall current of 12A. 

Featuring real carbon brushes and neutral timing.

A single package contains:

  • 1x motor

The key physical details are:

  • Dimensions (D*L): ⌀24.2*~34.5 + ~7mm shaft
  • Shaft dimensions (D*L): ⌀2*~7mm (measured from motor face. Stick-out from bushing ~6mm)
  • Face mounting holes: ⌀16mm M2x4 (note, not the typical 370 class pattern, but a lot more sensible)
  • Weight: 45g
  • Stamped steel housing with carbon brushes

Electrical attributes:

  • Input voltage: nominally 12V, 0.6-15V (ideal for 3s LiPo)
  • No-load RPM: ~25,000 RPM
  • Loaded RPM: ~23,000 RPM
  • No-load current: 0.33A
  • Working current: 0.4A-10A
  • Stall current: 12A
  • Stall torque: 0.35 kg/cm

We can supply this motor or any “standard” model of brushed motor like it in higher quantities. Please get in touch at if you require a custom solution at scale.
