Novak Crawler 21.5 Brushless Motor
Novak Crawler 21.5 Brushless Motor
Though Novak's 21.5 Brushless Crawler has many of the same great features as the updated #3419 Brushless Crawler 18.5 Sintered Motor, it has one key difference: It is even slower. With its lower-speed driveability and torque, the Crawler 21.5 Brushless Motor is equipped to tackle the harshest environments.
Features
The specially-designed Crawler motors scale over other brushed motors because of their massive start up and low-speed torque, all without sacrificing power or control. This eliminates the need to use 3-cell Li-Po packs, required by out-runner motors, which adds unnecessary weight to the rig. Novak's lightweight brushless system can tackle the most challenging terrain on 2-cell Li-Po packs.
Both Crawler motors include the same high-performance sintered rotor that Novak’s Velociti-series motors currently use. The rotor is ideal for use with any and all applications, and provides the following benefits:
Significantly increased magnetic strength for improved throttle feel
Improved, stronger motor braking power
Improved performance in higher temperature conditions
Improved motor acceleration and power
Higher efficiency
Lower current draw
Nickel-plated for a long lasting, smooth, clean finish
Additional features:
Sensor-based commutation for precise rotor position control
High-performance sintered rotor for stronger motor braking power and improved performance in higher temperature conditions
Oversized front bearing for extra durability and extended life
Ribbed aluminum end bells to reduce weight
Solder tab system for flexible soldering options
