FA-4088RB Coreless Brushless DC Motor
FA-4088RB is a flagship 150W super high-torque coreless brushless DC motor with 40mm outer diameter and 88mm ultra-long body. Equipped with heavy-duty double ball bearings and built-in 3-channel hall sensor, it delivers extreme stall torque for long-hour heavy continuous loads. It adopts industrial pluggable EX2EDG-5.08 8Pin Phoenix terminal with 16AWG thick silicone wires for stable high-current transmission. Four winding variants cover 32V, 36V and 48V high industrial voltages. EM22 incremental & absolute encoders are optional for high-precision closed-loop servo systems.

Engineering Overview
FA-4088RB coreless BLDC eliminates cogging torque and brush wear for ultra-smooth heavy-duty operation. Oversized rotor delivers extreme stall torque to handle ultra-hard cutting loads. Industrial pluggable Phoenix terminal supports high-current transmission, easy disassembly for maintenance. Reinforced ball bearings resist severe vibration and impact. It matches 32/36/48V industrial power supplies; EM22 encoders enable high-precision closed-loop position control.
Typical Applications:
• Heavy stone/metal industrial carving & cutting power equipment
• Large-load industrial robot main drive joints
• High-power professional industrial polishing machines
• Heavy-duty automated industrial transmission modules
