WST Series (IE5 IE4) Three Phase Super Premium Efficiency Permanent Magnet Motors

Product catalog summary

Overview: The WST Series Three Phase Super Premium Efficiency Permanent Magnet (PM) Synchronous Motors are engineered for superior performance and efficiency, adhering to IE4 and IE5 standards as per IEC60034-30, 2014. These motors utilize rare earth permanent magnets (NdFeB) to deliver high power density and excellent electrical characteristics, even under overload conditions.

Key Features:

High power density with constant torque across all speeds.
Efficiency exceeds that of induction motors at low speeds.
Equipped with EM30 inverter for environments with dampness, dust, or vibration.
Technical benefits include variable speed operation, precise low-speed control, low noise, and compact design.

Applications: Ideal for elevators, fans, pumps, conveyors, exhausts, electric vehicles, textile machinery, compressors, and other applications requiring speed variation, high efficiency, low noise, and reduced volume.

Technical Specifications:

Frame size: 71-355
Power range: 0.55-400kW
Speed: 1500-4500 r/m
Protection: IP55, Insulation: Class F, Temperature rise: B-level, Duty: S1
Rated voltage: 400V
Operating temperature: -20°C to 40°C, Altitude: ≤1000m
IE5 efficiency available upon request

Performance Characteristics:

Variable-frequency speed control with constant torque.
No rotor losses, low temperature rise, high efficiency (IE5, IE4).
High torque and power density, high power factor.
No encoder required, accurate speed control with synchro-speed.
Wide speed range supporting direct motor drive.

Technical Data Summary: Detailed specifications for various motor types are provided, including frame size, rated speed, power, torque, voltage constants, and efficiency percentages. Motors are categorized by speed (4500r/m, 3600r/m, 3000r/m, 1800r/m, 1500r/m) and pole count (6 Pole, 8 Pole), with efficiency ratings from 86.7% to 97.0%.

Mounting and Dimensions: Detailed dimensions for mounting and overall sizes are provided for frame sizes ranging from 71 to 315, including specifications for mounting holes, shaft dimensions, and overall motor length.

Bearings and Terminal Box: Specifications for bearings at the driving and non-driving ends are provided for each frame size. The terminal box dimensions and gland specifications are also included.
