Infranor MPM Sensorless Synchronous Motors
Infranor MPM Sensorless Synchronous Motors
MPM combines a buried-permanent-magnet synchronous rotor with an industrial motor housing. Infranor positions it for efficient sensorless operation with an appropriate inverter. It should not be treated as an ordinary induction motor that can be connected without the required electronic control.
Review Summary
Consider MPM for a defined pump, conveyor, spindle or other process duty when a supported sensorless drive and actual operating curve meet the requirement. Evaluate near-zero-speed and transient behavior explicitly; a broad efficiency or constant-torque claim does not resolve every control condition.
