Firma 20T Rebuildable 5-Pole Brushed Crawler Motor (SPMXSM5205)

Firma 20T 5-Pole Rebuildable Brushed Crawler Motor is a rebuildable brushed motor designed for 1/10-scale crawlers and scalers that run brushed ESCs. Housed in a 540-size can, it delivers smooth low-speed throttle control and efficient performance, making it a practical upgrade for crawl-focused rigs.

Its 5-pole design provides smooth throttle response and efficiency, with adjustable timing from 0 to 20 degrees for tuning in clockwise or counterclockwise rotation. Available in 16T and 20T configurations to balance torque and speed, it features pre-shaped curved-face brushes that require no break-in and comes with wires and 3.5mm bullets installed for easy hookup. Dual sealed bearings help keep out dirt, and the motor is fully rebuildable with an easily accessible commutator and replaceable brushes, springs, and bearings. For operation, a 2S LiPo or 6-cell NiMH pack is recommended.
