Yuma Precision continues to develop stepper motor cores, currently there are NEMA6 / NEMA8 / NEMA12 / NEMA14 / NEMA16 / NEMA17 / NEMA23 / NEMA24 / NEMA34 and other series, providing customers with sufficient model choices.
Benefits of Laminated rotor Design:
Reduced core losses: The laminated construction significantly reduces eddy current and hysteresis losses compared to a solid steel rotor.
Improved efficiency: Lower core losses in the rotor translate to higher overall efficiency for the electric machine.
Enhanced magnetic properties: The laminated steel allows for more efficient magnetic flux paths within the rotor.
Applications:
Laminated steel rotors are commonly found in:
Induction motors (squirrel-cage and wound-rotor)
Synchronous motors (including permanent magnet and wound-field types)
Generators (such as those used in power plants or wind turbines)
Rotor Design Considerations:
The number of rotor slots, rotor winding configuration, and other design parameters are optimized to maximize the motor or generator's performance.
Advanced rotor designs may incorporate additional features, such as copper bars or end rings in the case of induction motor rotors.
