FLDT Series Pole-Changing, Multi-Speed Three-Phase Asynchronous AC Motors
The FLDT series of pole-changing, multi-speed three-phase induction motors can achieve different pole numbers by altering the wiring connections. They are suitable for mechanisms requiring step-by-step speed control and offer advantages such as high reliability and ease of operation.
Description
The FLDT series of multi-speed, variable-pole, three-phase induction motors feature a single winding; by changing the wiring connections, the motor can be switched to different pole numbers, allowing it to operate at different speeds with varying output power.
The FLDT series motors feature high starting torque, excellent performance, low noise and vibration, high reliability, and ease of operation. FLD/FLDT series motors are widely used in applications requiring step-by-step speed control, such as compressors, processing equipment, conveyor systems, agricultural machinery, and food processing machinery. We also provide custom-designed multi-speed motors to meet specific customer requirements.
The operating conditions of the FLDT series motors are the same as those of standard three-phase induction motors.
