Frameless Torque Motor

KMF series frameless torque motor, which consists of stator and winding, high performance NdFeB rotor and Hall sensing circuit, can be used very flexibly and save application space, which makes it easy to realize reliable and tight system design. High torque density. The rated torque of the frameless torque motor with a stator stack thickness of 20 mm only and frame diameter of 145 mm is greater than 4 N·m and the maximum torque is greater than 11N·m. Ultra-low cogging torque ensures extremely low torque ripple at a low speed to realize low noise and precise rotation. 60 mm- 145 mm frameworks and 220 VAC and 48 VDC voltages are optional. Hall sensor is set inside to provide output of feedback signal.

Application Of Actuator In Automation Industry ---- CNC Machine

Working conditions:

Load ≦ 20KG, Output speed: 5-10r/min

Attention:

1. This product is integrated with a harmonic drive, which has high operation accuracy, but its load is limited, which couldn't be exceeded.

2. Encoder and motor are integrated, which can adapt to most of the control systems on the market and support a variety of communication protocols.

3. The environment temperature is - 10 ~ 40 ℃, the humidity is below 85%, and the ventilation is good. Although it has the protection grade of IP65, it is not suitable for the place where the liquid is sprayed directly.

Advantages:

The traditional dividing plate is driven by the planetary reducer. Although the planetary reducer is cheap and can reduce the cost of the whole machine, the accuracy and accuracy maintenance ability of the dividing disc of the planetary reducer has gradually failed to meet the increasingly high processing requirements of the industry. The all-in-one actuator integrated by Y-series harmonic drive, frameless torque motor, and encoder developed by our company for machine tool and machining center industry is adopted to solve the problem of substandard accuracy. It has the advantages of a compact and hollow structure, easy cable passing, and high torque output. The protection level is up to IP67 and could match a variety of communication protocols. Moreover, compared with the common harmonic drive, the Y-series has high stiffness and a service life of more than 20000 hours.

Future trend:

Our actuators are widely used in electronic and semiconductor equipment, precision CNC machine tools, precision laser processing equipment, testing equipment, medical equipment, printing machinery, glass processing equipment, precision measuring instruments, and other fields. In recent ten years, due to the strong support of the state for the machining industry and the drive of the manufacturing industry, the CNC machine tool industry has developed rapidly. Large scale, high speed, and high precision have become the mainstream of CNC machine tools. The technology of key components of the machining center is also higher and higher. The traditional linear axis machining changes to five-axis rotary machining.
