Frameless Motor
This hollow shaft motor allows the design to be tailored to the application.
ShinMaywa 's frameless motors (with built-in rotors and stators) are developed using the latest technology to meet "true needs." We have established a delivery system that can fully accommodate detailed specifications and requirements depending on the intended use. Frameless motors are available in 10 types with outer diameters from 30mm to 570mm, more than 10 types with core thicknesses from 6mm, and 16 types of winding patterns, allowing us to manufacture more than 60 types of motors. Furthermore, we can perform molding and skew processing of the rotor and stator according to the application. ShinMaywa 's frameless motors support flexible mechanism design.
- Frameless structure offers excelient design flexibility of hollow shaft motors.
- The large inner diameter of the rotor ensures efficient use of the center section and saves space.
- For a direct drive application, the vibration and changes in rotation speed caused by backlash, lost motion, friction torque, transfer torque ripple, insufficient rigidity, etc. are greatly reduced compared with the conventional drive system using a reduction unit.
- No deterioration with age such as wear, and the small number of parts facilitates inspection and maintenance.
Housed motor
We also respond to requests for housed motors incorporating frameless motors. Depending on the required shape and rotation speed, we can handle everything from selecting an encoder with an appropriate shape to custom designing a rotor shape. We also handle drivers from high-end to low-end depending on the required specifications. In addition to spindles that use air bearings from various companies, we can also integrate motor rotors and rotating shafts, and custom-order stator cases.
