คุณสมบัติของมอเตอร์เกียร์S-PM Series

What are S-PM motors?

S-PM motor is a synchronous motor incorporating a strong permanent magnet in the rotor.
It does not slip like an induction motor (which drops in rotation ความเร็ว under increased load), making it suited for การควบคุมling ความเร็วs with high precision.
Additionally the rotor is the permanent magnet, so there is no secondary copper loss (rotor loss) as occurs with induction motors, and it maintains high motor efficiency.

What is sensorless การควบคุม?

Sensorless การควบคุม is a method for การควบคุมling a permanent magnet motor by estimating the rotor position (magnet position) and ความเร็ว in the drive unit instead of using a sensor (encoder). ความเร็ว can be การควบคุมled with high precision even without a sensor (encoder) thanks to the PM sensorless vector การควบคุม equipped with Mitsubishi Electric’s proprietary adaptive magnetic observer *1

*1The adaptive magnetic flux observer scheme is a การควบคุม method in which a virtual motor model is included within the drive unit and detects the ความเร็ว and magnetic pole position within the motor based on its voltage and electric กระแส.
