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.
