Features

1. The transmission error is small. The length of the main drive chain of the machine tool is zero, the motor directly drives the spindle, without any transmission error, the spindle vibration is obviously reduced, and the surface finish of the workpiece is obviously improved.
2. Power ratio is large, constant torque range is wide, and high response speed. The motor is a rare earth permanent magnet synchronous motor with extremely high power density and torque density. Compared with asynchronous motors, the response speed is extremely high. The motor has a large power density and a wide constant torque range. Under the same volume, it is larger than one power level of the asynchronous motor.
3, built-in direct drive structure design, flexible power configuration. The motor is inside the main shaft, and the power of the motor can be arbitrarily matched with the thickness and length of the main shaft. It is extremely flexible and can be used in various radial space limitation applications. 4, the speed range is wide. The motor can realize an extremely wide speed range, and stepless speed regulation can be realized between zero speed and maximum speed.
5. High productivity. The motor has excellent low-speed hard characteristics. Under the permission of bearing rigidity and tool hardness, it can be used for hard metal, low-speed large-scale cutting, high-speed snack knife precision cutting, and greatly improved production efficiency. 6, the servo is strong. With the dedicated driver, all functions of the digital servo spindle can be realized, such as rigid tapping, quasi-stop positioning, motion control and so on.
7. Support flange and base installation methods.
