YR series (IP23) motor for the protection of wound rotor three-phase asynchronous motor, which, YR400 is the latest design of low-voltage high-power motor. Motor power rating and installation dimensions in line with IEC international standards, enclosure protection class IP23, cooling method for the IC01, continuous working system (S1). Suitable for non-flammable, explosive, corrosive gases and more clean natural place.
This series of motors can provide a large starting torque at a small starting current, and can adjust the speed in a certain range, can be widely used: (1) need more than the cage rotor motor greater starting torque; (2) the feeder line capacity is not enough to start the cage rotor motor; (3) start a long time and start more frequently; (4) need a small range of speed; (5) into the "shaft" for synchronous transmission The Such as: winch, hoist, wire drawing machine, compressor, ball mill, sugar machine, hoist, conveyor belt and other heavy-duty start, short-term operation of the mechanical equipment.
This series of motors with high efficiency, overload capacity, low noise, vibration, reliable structure, beautiful appearance, etc., especially for external exports, and imported equipment, matching. This series of motors is used to replace JR, JR2, JR3 and other old series of winding rotor motor upgrade products, is to achieve energy saving, improve the host level of technical and operational reliability of the ideal product.
The motor adopts B-class or F-class insulation, rated voltage of 380V (also made 660V), rated frequency of 50Hz, the stator for the △ connection (660V when the Y connection), the rotor Y connection. The structure and installation of the motor type IMB3 (base with a foot, no cover flange, horizontal). Stator outlet: H160-315 side outlet; H355-400 outlet line.
This series of motors can be pressed directly to start, but at the start of the rotor circuit must be connected to start rheostat or frequency resistors, start the normal operation of the rotor winding should be the three lead-out short. Do not allow direct short-circuit start-up in the collector ring or brush holder (including three lead wires). The following figure shows the wiring schematic for starting the rheostat (for reference).
