A synchronous motor has a rotor that typically rotates at the same rate as the machine’s rotating field. The stator resembles an induction machine in that it has windings, often three-phase, that are arranged in slots around the inner periphery of a cylindrical iron frame.
A synchronous induction motor is a combination of both a synchronous motor and an induction motor. Synchronous induction motors can be employed in situations that call for high starting torque and steady speed. It benefits from both synchronous and induction motor advantages.
In contrast to induction motors, which can be started against full load torque, synchronous motors provide steady speed.
Benefits of synchronous induction motor
The global Synchronous induction motor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
To accommodate future long-distance electric vehicles, Vitesco Technologies is introducing an externally excited synchronous electric machine (EESM) that doesn’t use rare earth metals and is made for high ranges and quick highway driving.
The world’s first high-efficiency synchronous reluctance (SR) motor with an aluminum cage has been introduced by Nidec Corporation as SynRA (Synchronous Reluctance Motor with Aluminum Cage Rotor). SynRA combines the fundamentals of an SR motor with those of a cage-type induction motor.
When connected to a commercial power source, the cage-type induction motor, utilized as a general-purpose motor for industrial applications, can be turned on. The motor is used in fans, pumps, compressors, cranes, elevators, and many other industrial machinery since it is inexpensive to produce and does not require an inverter (a device to adjust rpm).
The International Electrotechnical Commission (IEC) has established a new level of efficiency called ultra-premium energy efficiency, and ABB IE5 synchronous reluctance motors (SynRMs) are the top choice to satisfy this demand. ABB provides two SynRM product lines: IE5 SynRMs with an output of 5.5 to 315 kW in frame sizes IEC 132 to 315; high-output SynRMs with an output ranging from 1.1 to 350 kW in IEC 90 to 315;
In addition to having up to 50% fewer energy losses than IE2 motors, ABB’s IE5 ultra-premium SynRMs also use much less energy and emit significantly less CO2 than the more widely used IE2 IMs.
