1. Geneal


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.

2. 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.


Normal operation conditions for motor:

(1) sea level is not over 1000m

(2) the highest ambient temperature is not over 40 °C,the lowest ambient temperature is -15°C

(3) In moist month,the monthly overage highest relative humidity is 90%,at the same time,the monthly overage lowest temperature is not over 25 °C

(4) The frequency of power source is 50HZ ±1%

(5) The vaiation fo work voltage is not over rated voltage ±5%

(6) Moto rating is continuos operation system S1.


3. Type description


The motor type is composed of the product code and size in accordance with the regulations of GB4831. The product code is represented by the motor series code which meaning is show as belows:

Y----- squirrel cage motor three-phase induction motor

YR----wound rotor three-phase induction motor

The size code is composed of the center height,core length sequence and pole quantity.


4. Construction description


The frames and end-shields of this series motors adopts high rigidity casting iron, the stator employs the externally pressing structure , stator winding( H315,355) consists of flat copper formed hard coil or circular copper formed random coil, it employs class B Or F insulating materials , the fixing of winding terminals employs the special binding process,fixed and reliable .The whole stator is treated by the vacuum pressure impregnation (VPI) F solventless paint. thus, the motor has the excellen and reliable insulation performance,damp-proof and shock resistance.

The squirrel cae motor in this series motor mostly adopts cast aluminum rotor,running reliable,the wound rotor employs the F-Level insulation material and uses the vacuum pressure impregnation F-level solventless paint(VPI) for treatmnt.

The motor employs the rolling bearing structure and the basic proteciton is IP23

The motor (315-355) has the special oil filling tools may be used for filling and exhausting the oil without stopping the machine,

The mail teminal box employs the sealed structure, and the protection class is IP 54, They are generally installed in the right side of motor(view facing shaft end of the electric motor). it also can installed in the left side of motor according to the requirement of users.The box has the separate grounding terminals.


5. Stating of squirrel cage type induction motor


The squirrel cage motor of induction motor have adopted the advanced computer techique to calculate the starting temperature and pressure of the squirrel rotor,thus avoid the motor's destroy at a early period because of the motor 's overloaded while starting.so we suggest users to check the items as belows:

(1) The moment of inertial (after being converted to motors rotating speed) of the rotating part of the driven mechanical equipment should not ove these values item shown in the technical table;

(2) Customer's should guarantee the voltage of electric network across the motor's terminals not lower than 85% of the rated value during starting;

(3) The resistance moment feature of driven machines is the resistance moment feature of water pump and fan.


Under the above mentioned conditions,motor may be permitted to be started at actual cold condition for twice continuously ,or at hot condition for once,the interval of two times starting is natural stoppage,if there is need to start over above limit,it must wait for one hour.


if the moment of inertia of the mechanical rotating part of the machinery being drive is over the value shown in item of techinical data, or there is a requirement to start motor frequently ,or it is possible to start the motor under heavy loading,it is necessary to contact with our company for negotiating about specification design so as to ensure the reliable start-up fo motor.
