FMK Highly Integrated Robot Joint Frameless Torque Motors

Name: FMK Highly Integrated Robot Joint Frameless Torque Motors
SKU: -1

● Introduction

Frameless torque motors, unlike traditional servo motors, consist only of stator and rotor components. Compared to framed motors, frameless motors offer flexible configuration and easy installation. Considering the increasing trend of highly integrated drive systems, frameless motors better meet the expectations of engineers. Engineers no longer need to consider motor interfaces in system design, allowing for maximum reduction of space occupied by the power output unit in the drive system, leading to higher system integration.The HONPINE FMK frameless torque motors are now widely used in the J1–J6 joints of collaborative and dual-arm robots, the walking joints of quadruped robots, and the flexible joints of humanoid robots.

Designer Speaking

In response to customers' increasing demands for core joint components, HONPINE has launched the fourth-generation FMK series frameless torque motor.FMK series frameless torque motor has optimized the stator welding process, enhanced the roundness of the stator, and ensured superior performance while minimizing the motor length to meet the usage requirements of customer. In addition, the motor has been upgraded with a larger split ratio and a larger hollow design, and its rotor manufacturing process has been optimized, making it more suitable for embodied intelligent product and effectively reducing customers' overall TCO . Meanwhile, the FMK series frameless torque motor has further expanded its size coverage, basically covering the size specifications of mainstream joint modules on the market, thus making the size options of HONPINE's frameless products more comprehensive.

Features

● The size coverage has been upgraded again!The outer diameters of the fourth-generation FMK series products

include25/38/43/50/60/70/85/115/140/160mm;

● The large split ratio and large hollow design,along with the larger inner diameter of the rotor,are more suitable for the

wire passing and board layout requirements during the mechanicaldesign of humanoid robots

● The process update reduces the weight of the motor and increases the power density,and contribute to the

lightweight development of customer's embodied intelligence product overall weight control.

● The temperature rise performance is excellent.The potting process and electromagnetic optimization bring excellent

temperaturerise control.

● The noise and vibration performance is excellent,bringing a good experience to the movement coordination of

embodied intelligence products.
