Jasung Gearless Motor Pulley - Permanent Magnet Belt Conveyor Drive​ 60-160kW

PMDD pulley description

Here's a refined version of your description with improved clarity and flow:

The Jasung outer rotor permanent magnet motor technology features a unique permanent magnet direct drive (PMDD) pulley design. In this configuration:

Stationary Component (Stator Equivalent)​​

◇The central shaft remains fixed, functioning as the motor's stator assembly

◇A laminated stator core, constructed from precision-stacked silicon steel sheets, is securely mounted on the shaft

◇The core contains embedded three-phase stator windings that generate a rotating magnetic field when energized with symmetrical AC current

Rotating Component (Rotor Equivalent)​​

◇The pulley surface serves as the motor's rotor element

◇A rotor assembly composed of laminated silicon steel sheets is fixed to the pulley's inner surface

◇High-performance UH-grade permanent magnets are embedded within the rotor structure, creating a persistent static magnetic field

​​Operational Principle​​

When three-phase symmetrical alternating current is applied to the stator windings, the interaction between the rotating magnetic field and the permanent magnets produces torque. This electromagnetic interaction drives the pulley's rotation, enabling motor operation without requiring additional transmission components.

The direct drive design offers enhanced efficiency and reliability by eliminating mechanical transmission losses associated with conventional drive systems.
