The type of product were composed of four parts .There are the product code, the specifications code, the special circumstances code and supplementary code. They are arranged in the following order: the products code - the specifications code - the special circumstances code - supplementary code.一、 Product Code: were composed of four components of the order。There are the type of electric motor code, the characteristics code of electric motor, serial number of the design, and the code of exci

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 (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 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

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

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
