Hobbywing AXE 540L R2 FOC Sensored Brushless Crawler Motor 2100Kv

The Hobbywing AXE 540L R2 FOC Sensored Brushless Crawler Motor 2100Kv (HW30401254) brings the AXE System’s advanced control and durability to rock crawlers. This 540L R2 motor is sealed and features a redesigned sensor harness and waterproof sensor port, helping deliver reliable performance across varied weather and track conditions.

Applicable to All Weather & Track Conditions

Waterproofing has been taken to a new level within the AXE System. The motor is sealed and uses a completely new sensor harness, so there are no messy extra steps needed to make your setup waterproof. After running in harsh conditions, dismantle and clean the motor and apply lubricant to the bearings.

Built-In High-Precision Magnetic Encoder

A high-precision magnetic encoder feeds accurate, consistent data to the ESC. This provides more information than standard hall-type sensors and supports improved performance and efficiency.

Low Cogging Torque

AXE R2 motors are engineered for extremely low cogging effect and reduced torque pulsation.

New Waterproof Sensor Port

The latest waterproof sensor port is smaller and streamlines wiring compared with the earlier AXE R1 system.

Available in Different Sizes & KVs

The AXE R2 motor line covers multiple options for rock crawlers: 540L R2 in 1400Kv, 2100Kv and 2800Kv, plus a 550-size 3300Kv variant.
