Description
The RUDDOG Crawler 20T 5-Slot Brushed Motor is a 540-size brushed motor developed for crawler and scale vehicles that demand exceptionally smooth power delivery, precise throttle modulation, and strong low-end torque. Its 5-slot design provides refined power transfer and outstanding control at very low speeds.
Compared to the 13T and 16T versions, the 20T winding offers increased torque and reduced wheel speed, making it an excellent choice for technical crawling, rock sections, and heavier scale builds. The smooth power characteristics allow drivers to maintain precise control even in the most demanding terrain.
Dual ball bearings ensure smooth operation and long-term durability, while replaceable brushes and springs make maintenance straightforward. Cooling fins improve heat dissipation under load, and adjustable timing allows the motor rotation direction to be changed for vehicles with unique drivetrain layouts.
