Description
The RUDDOG Crawler 45T 3-Slot Brushed Motor is a 540-size brushed motor developed for RC crawler and scale vehicles, delivering high torque and excellent low-speed control for technical terrain. The 45-turn winding is ideal for drivers seeking precise throttle modulation and maximum climbing capability.
Its 3-slot design provides strong power delivery and responsive throttle feel while maintaining smooth operation in demanding crawling conditions. Dual ball bearings reduce friction and improve long-term reliability.
Replaceable brushes and springs make servicing straightforward, while integrated cooling fins help dissipate heat during extended runs. Adjustable timing also allows the motor rotation direction to be changed, making it suitable for vehicles with special transmission configurations.
