FMK1 Cost Effective Frameless Brushless DC (BLDC) Motors

Name: FMK1 Cost Effective Frameless Brushless DC (BLDC) Motors
SKU: -1

● Introduction

HONPINE FMK1 Frameless Brushless DC (BLDC) Motors are compact, high-performance, and cost-effective products. Available in four sizes (φ50mm–φ115mm), with rated speeds ranging from 650 rpm to 5250 rpm, torque from 0.3 Nm to 9.32 Nm, and power from 165 W to 920 W. Rated voltages range from 24 V to 70 V, with optional Hall sensors, temperature sensors, and wiring configurations. They are widely used in collaborative robots, humanoid robots, quadruped robots, and medical rehabilitation robots.

Features

●Ultra-High Torque Density

Torque increases by 10% under the same input current, leading the industry.

●Extended Endurance

Optimized magnetic circuits and material selection reduce motor losses and prolong operational time.

●Ultra-Compact Structure

Removal of the housing and redundant components reduces volume by 40–50% compared to industry standards, better suited for high-density layouts.

●Ultra-Low Inertia

Lightweight design and innovative use of composite materials enable rapid dynamic response, ideal for high-frequency start-stop scenarios.

●Ultra-Low Temperature Rise

Optimized magnetic circuit design reduces motor losses by 20%, significantly improving energy conversion efficiency.

●Easy Integration

Compact design allows flexible installation and seamless embedding into various mechanical systems, accelerating development and improving performance.
