Ball mill motor
Y, YR 280-355(IP23) series small sized low voltage high power three-phase induction motor is the latest designed series motor. It has pleasant appearance, unique mode, some of its technical economy indexes have reached the international leading level. The products have been produced in a large volume and exported to more than 20 counties and regions, even all over the countries, they have got the good appraisal form the users.
This series products adopt the high quality materials, good manufacturing pocess, have the charcteristics of high efficiency and enegy-saving, small vibration, reliable operating and convenient for mounting and maintenance etc,
The power grade, electric propety, mounting dimentions and tolerance are coincident with natinal standad GB755 Rotating electric motor rating and propety, international electrical Committee standard IEC 34-1 Rotating Electric Motor Rating and Property, and machinery industry standards JB 5272-91. JB 5269-91 etc.
The out cover protections of this series of motor is IP55 in accordance with the standard of GB 4942.1 and IEC 34-5 enclosure protection levels of Rotating Electrical Machine.
The cooling method is IC01 in accodance with the standard of GB/T1 993-93 and IEC 34-6 cooling methods of Rotating Electrical Machine.
The structure and installation method of this series of motor is IMB3(horizontal with footing, end shield without flange). IMV1(shaft extension downwards and lower end cover with flange), and complies with the specifications of GB997 and IEC 34-7 motor structure and mounting cope type.
This sample table lists the technical data and istallation sizes of 380v grade series motor, and may derive the 440v and 660v grade motors in all sizes.
YR winding horizontal motor Application Ranges
This series of motor may be used for driving all kinds of general machines such as the compressor, ventilation fan, water pump, stock-removing machine, transportation machines and other mechanical equipment, and are applied as the prime mover in all industrial and mining enterprises such as the mine, machinery, petrochemical industy and power plant etc, if the users place an order for the motors that ae used to drive the machines with huge rotary intertia such as the blower, coal grinder, rolling machine, crushe, belt machine, etc, they shall provide us with relevant technical data, sigh the technical agreement with us as the basis for specific design of motor to ensure the reliable operation for motors.
The YR(IP23) series electric motor is capable of providing relatively large locked rotor torque under relatively small locked rotor current, and regulating speed within limits, it apply to the following situations extensively: 1 the large locked rotor torque is required than squirrel cage type motors; 2: The capacity of transmitting line is insufficient to start squirrel cage type electric motor; 3: Long starting time and frequent starting; 4: The speed regulation is required within small range; 5: Synchronous rotation with electric Axis, formed by unity. Such as: Compressor, presser, winch, bedrench, conveyor, printing machine etc.

1.Please indicate the motor type,rated output,rated voltage,rated frequency,synchronous speed,Explosion proof Mark,mounting type,rotation direction(view from the shaft extension side)Use of the environment(indoor or outside)If the user havn't point out the rotation and environment,normailly we think is CW roration and used indoor.
2.when user have special requirments,For example:Dispose the stator,bearing explosion proof and bearing temperature sensors,space heater,Plateau use,specical frequency,mounting size change,special output,the user must ,order can be confirm after signing the technical agreement with engneering department .
3.The catalogue is only for reference,and there may be variations.
4.This range of motor can also be made into Variable-Frequency motors,the range of frequency of which is 0-100HZ,the output and overall dimensions should be confirm separately.
