The Holmes Hobbies CrawlMaster Magnum 540 Brushed Electric Motor is a high torque, 11 Turn option that offers the smoothest startup of any Holmes motor, with faster wheel speed than a TorqueMaster Pro 540 27t.

The Magnum is a performance oriented brushed motor designed with a larger rotor diameter and more powerful Neodymium magnets when compared to the regular TorqueMaster and CrawlMaster Pro 540. This motor is fully rebuildable and compatible with many Holmes 540 motor end bell parts.
