GM7 series of AC servo spindle motor can be used with various high, medium and low-grade spindle AC servo drives to perform closed-loop control operation and achieve excellent performance. GM7 AC servo spindle motor is widely used in the fields that requires AC servo spindles such as CNC machine tools, building materials, blow moulding machines, textile, light industry, metallurgy, transportation lines.
GM7 series of AC servo spindle motors consist of stator, rotor, low-noise fans, and high-precision encoder (not required for open-loop control). Based on the structural optimization design and magnetic circuit optimization, GM7 series of AC servo spindle motors adopt the special class F insulation, complete machining, and high-precision dynamic balancing process.
1. Compact structure, small size, light weight, and high power density
2. Special design, small electromagnetic vibration, low noise, high rotation precision, constant torque and wide constant power speed range
3. Small rotor inertia and rapid response
4. Uniform air gap, high-precision balance, small torque ripple
5. Fully sealed design, high protection class (IP54)
6. Special Class F insulation, anti-surge current and anti-corona, long life, and reliable operation
7. High price and performance ratio
