  • About the handling of high-voltage electrical wiring

    High-voltage motors’ voltage level is usually as high as 6kv or 10kv, so the insulation of the cable in the junction box of the motor’s main power is very important. The motor’s connection cable is divided into two parts, one is the outlet cable of the motor’s stator and the other part is the power supplying cable while the motor is running. As provided in the national standard GB14711-2006 “ Security requirements of small and medium-sized rotary motors”, for the motor with 6kv rated volta

  • An example of lack-phase motor

    piece of Y160L-4-15KW three-phase asynchronous motor, triangle connected, it can start in the past time, and now can not start with a strong noise. If be rolled, it can run along the external force, but quickly overheated. Analysis:as it can run along the external force, we know that the motor lack phase.When triangle connection motor lack phase, the off-phase winding into currentcircuit. in the same voltage, the current is same. so the motor will not start. At this time, not off phase winding c

  • Motor maintenance knowledge 2

    Three-phase asynchronous motor should not the normal operation of the fault analysis steps Units 1 Y160L-4-15KW three-phase asynchronous motor, should not the normal operation of the steps at the time of failure analysis. When a motor can not be normal operation, it is necessary to fix it, we must follow the steps must check,that is, in a systematic to do some tests, find out the root cause of failure.After these tests, repair personnel will be able to determine whether this motor is only requir

  • The basic principles for selecting motor

    Motor mechanical properties, start, brake, speed control and other control performance should meet the mechanical properties and production process requirements ,when the motor power supply quality (such as voltage fluctuations, Xie interference, etc.), should be in the extent permitted. Work as scheduled system, the cooling method of Kiev in the case identified by the motor power, motor temperature rise should be limited to the framework. According to the environmental conditions, operating c

  • Ybk2 series three-phase explosion-proof low voltage induction motor introduction

    YBK2 series three-phase explosion-proof low voltage induction motor (frame 100-315) is the same as YB2 series motor at technical data; the difference is that YBK2 series uses armor plate jointing frame. So it is good at Strength and hardness and mainly used for coal mining . YBK2 series three-phase explosion-proof induction motor are made according to GB3836.1-2000 Electrical apparatus for explosive gas atmospheres-Part 1: General requirementsand GB3836.1-2000 Electrical apparatus for explosive

  • Yb2 series three-phase explosion-proof induction motors introduction

    YB2 Series 3-Phase Explosion-proof Induction Motors (frame 80-355) is Replacement products of YB series; it summarizes the experience of YB series, using lots of advanced technology such as computer aided design (CAD), insulation, machine design, explosion-proof design, arts and crafts, good material and testing. YB2 series motors have better performance, more aesthetic appearance; it is the ideal choice for general power equipments YB2 series 3-phase explosion-proof induction motors is made acc

  • Thermal protection for motors

    1、BriefCommon thermal protection components for medium-small size motor include PTC thermistor, PT100 temperature sensor and bimetallic temperature relay. Also include damp-proofing heater, for heating inside of motor in damp environment. These components are buried inside of motor, like windings, or bearings caps at DE and NDE sides.If windings and bearings are caused higher temperature when motor is in higher voltage, lower voltage, over current, lack of phase or overload, this signal can be

  • The maintenance of electric motors

    Maintenance is quite important for reducing and avoiding failure when motors are running, Thereinto, the most important link is patrol inspection and clearing the roots caused by any abnormal phenomenon. That is absolutely necessary to analyse the accident and adopt countermeasure for reducing accidents and raising efficiency when repairing resting table. Althouth the maintenance is very important, there are still many emergencies, such as short-circuit, overloading and lossing of phase. In thos

  • Motor maintenance knowledge

    1. How to dry the dampened motors?It is best to send the dampened motors to specialized repairing center for drying. If it is impossible, you can treat with the motor by yourselves. The motor can be connected with 220V single phase power supply, i.e., three entry cables connected with single-phase live wires, other exiting cables connected with neutral wires. If the motor is slightly dampened, it will take two hours, if it is seriously dampened, it will take one or two days. After drying, to use
