Sensorless operation allows for stable speed control comparable to servo motors
This product combines an S-PM motor (permanent magnet motor) with Mitsubishi Electric’s unique sensorless vector controller to achieve high-precision speed control.
With a ±0.05% speed variance rate that is comparable to a servo motor, it can be put to use in conveyance applications that require high precision such as on semiconductor and liquid-crystal production lines that induction motors cannot handle.
Premium efficiency compliant with IE3
S-PM motors are high-performance, energy-saving motors with a strong permanent magnet (high-performance ferrite magnet) in the rotor.
The motors are compliant with the IE3 high efficiency standard for induction motors and can reduce the energy consumption of equipment.
