Low Moment Of Inertia PMSM AC Motor 380V
Product Description:
-
A Permanent Magnet Synchronous Motor (PMSM) is a type of alternating current (AC) motor that utilizes permanent magnets embedded in the rotor to generate a magnetic field, eliminating the need for external rotor excitation. This design offers superior efficiency, power density, and dynamic performance compared to induction motors or brushed DC motors.
Features:
1. High efficiency: Because the rotor's magnetic field is constant, there are no slip losses like in induction motors, resulting in high efficiency.
2. High power density: PMSMs can achieve high torque and power output in a compact size.
3. Precise control: The synchronous nature of PMSMs allows for precise speed and torque control.

Similarities & Differences:
Similarities to Brushless DC Motors (BLDC):
PMSMs are often considered the AC counterpart of BLDC motors, sharing the same basic structure (permanent magnet rotor and wound stator).
Differences from BLDC:
PMSMs use sinusoidal back EMF and stator current, while BLDC motors use square wave drive and trapezoidal back EMF.
Packing and Shipping:
Each fan is securely wrapped and placed in a sturdy wooden box with ample cushioning material to prevent any damage during transit, and 6 sets of MOTORS are packaged with a wooden box.
