GM7 series AC servo frequency conversion (spindle) motors are composed of stator, rotor, low noise fan and high precision encoder (not needed for open-loop control). On the basis of structure optimization and magnetic circuit optimization, F-class special insulation structure, whole machine processing and high precision dynamic balancing technology are adopted.

It has the following advantages：

1. Compact design, smaller body, lighter weight, high energy density

2. Special design for electronics-magnet vibration, low noise, high rotation resolution, enough constant speed range and constant power range

3. Low inertia, high response

4. Even air-gap, high balance accuracy, low torque wave

5. Full sealed design, protection class:Ip54

6. Special Class F insulation, anti surge current&corona.

7. Robust, durable, reliable;

8. Good price based on strong performance.
