CrawlMaster BL 540 Stubby 10-Pole Sensorless Rock Crawler Motor 2700kv

 

Short motor, Smooth Startup, Sensorless inrunner reliability!

When you need a smooth and efficient sensorless motor but don’t want the noise or spinning can of a Revolver, the Crawlmaster 540 Stubby delivers! This 10 pole topology is tuned for competition and discerning drivers, with refined startup and low end control you expect from Holmes! The Stubby is shorter and lighter than standard 540s without sacrificing power or torque, it is an optimized performance choice in the inrunner style.

Top features include very controllable startup, higher efficiency than outrunners (but at lower torque density), sealed can design for messy use, 8 way mounting for the perfect install, beefy solder tabs for lower resistance, and oversized bearings to prevent premature failure.

Features:
  • Ten pole 16mm length Kevlar wrapped rotor with 180c rated magnets
  • Twelve slot stator with 200c rated resin impregnated coils
  • 14g phase wires with higher quality 4mm compression bullets installed
  • Oversized ABEC-7 bearings
  • Sealed can
  • 8 blind mounting holes
  • Shorter than a normal 540 motor
Specs:
  • 25mm 8 hole mounting pattern
  • M3 mounting screws (5mm depth max, we recommend using 6mm screws for most installs)

  • 36mm diameter
  • 45mm length
  • 149g (5.26oz) with wires
  • 50,000 rpm max
  • 2-4s lipo recommended
