Frequently Asked Questions (FAQ)
Q: What does "8/6/4 pole" mean for this motor?
A: The 8/6/4 pole configuration indicates that this is a 3-speed motor. By changing the wiring connection (via a multi-speed switch or contactor), the motor operates at 8 poles (710 rpm), 6 poles (950 rpm), or 4 poles (1440 rpm) to match the required load and speed of your machinery.
Q: What are the typical applications for the YD series multi-speed motor?
A: These motors are highly versatile and are commonly used in applications such as conveyor belts, centrifugal pumps, ventilation fans, and metalworking machinery where different operational speeds are required without needing an external VFD (Variable Frequency Drive).
Q: Why is the copper coil thickened by 30%?
A: Thickening the copper wire reduces the electrical resistance inside the motor. This directly lowers the temperature rise during operation, improves electrical efficiency, and increases the motor's overload capacity, preventing burnout under heavy-duty cycles.
Q: How do I mount this motor?
A: It features a standard horizontal foot mount (B3). The base hole distance is 190mm x 140mm with a center height of 112mm. Ensure the mounting surface is flat and level to prevent vibration and ensure proper alignment with the driven equipment.
Q: Does the motor come with a junction box for wiring the different speeds?
A: Yes, standard industrial 3-speed motors are equipped with a junction box designed to accommodate the necessary wiring configurations and speed-switching contactors required to safely operate the 8, 6, and 4-pole windings.
