FAQ

Q：What advantages does YQ/JS motor have over ordinary squirrel cage motors?

A：The YQ/JS series offers four key advantages: High starting torque with low starting inrush current prevents voltage drops in your power grid; stepped smooth speed regulation through external resistors provides economical control; capability to handle instantaneous heavy load impacts from ball mills and winches; and suitability for frequent start-stop operations with high-torque output requirements.

Q：What equipment is YQ JS series motor suitable for?

A：This series is specifically recommended for mining ball mills, lifting winches, heavy belt conveyors, metallurgical crushers, and port heavy lifting equipment. It's not ideal for ordinary fans, water pumps, or long-term light-load variable frequency speed regulation applications.

Q：Why does the YQ JS motor overheat and run at low speed under rated load?

A：Common causes include: three-phase power phase loss or low voltage; incomplete removal of rotor resistors leaving redundant resistance in the circuit; poor contact between slip rings and brushes increasing rotor loss; or blockage of rear mechanical equipment causing prolonged motor overload. Systematic troubleshooting of these areas typically resolves the issue.

Q：Can YQ JS wound rotor motor be matched with frequency converter?

A：Yes, but simultaneous use of resistance speed regulation and frequency conversion is not recommended. For frequency conversion control, rotor slip rings must be fully short-circuited and parameters configured as a standard asynchronous variable frequency motor. Applications requiring both heavy-load startup and variable frequency speed regulation need customized control systems and motors with reinforced insulation windings to prevent insulation breakdown from rotor high voltage.
