Parker PARKER explosion-proof click the EX series more suitable environment applications, such as: printing machinery, paint, plastics machinery, chemical, petrochemical, pharmaceutical, waste treatment plants 
 PARKER explosion-proof servo motor EX Series Parker, Parvex's EX permanent magnet synchronous servo motor series, for use in hazardous environments. Has a powerful explosion-proof shell, the EX motor can carry an internal explosion, but on the surrounding environment without any risk 
 EX motors are available in two versions, both North American and European safety standards. 
 10 pole rotor design of PARKER proof servo motor EX Series is based on the innovative, excellent quality of the body of the EX motor, power range, high acceleration and deceleration capacity, wide speed range, a variety of winding configurations, with maximum flexibility.

 The explosion-proof motors explosion-proof motor is a motor, a flammable and explosive factory run-time does not produce sparks. Explosion-proof motor is mainly used for coal, oil and gas, petrochemical and chemical industry. In addition, textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other departments have been widely used. Explosion-proof motor as the main power equipment, usually used to drive pumps, fans, compressors and other mechanical transmission. 
 Start: full voltage direct start, you can also Reactor and self-coupling transformer step-down start, but then reduced starting torque and voltage proportional to the square. 
 Coupling: If the motor with the load, should normally be full pressure start using coupling rotates the motor shaft centerline and drag the axis of the center should be consistent, the deviation should be less than 0.02, otherwise cause bearing damage and shaft fracture. 
 Installation: The following factors should be considered in determining the location of the explosion-proof motor: explosion-proof motor should be installed in a well-ventilated place, an ambient temperature of -15 ° C to 40 ° C, altitude ≤ 1000m; import and export should not pay attention to explosion-proof motor exhaust hot air into the air inlet to generate repeat the cycle, or a motor exhaust hot air directly into another motor; should ensure that the motor around the workplace in order to facilitate the disassembly, cleaning or inspection. 
 Material requirements: the manufacture of Class I with the motor housing of light metal material by mass percentage of the total content of aluminum, titanium and magnesium does not allow more than 15%, and the total content of titanium and magnesium does not allow more than 6%. Class II with the motor housing of light metal material by mass percentage, the amount of magnesium does not allow more than 6% 
 Distance requirements between the various components: the distance between the explosion-proof motor fan, outer fan, fan cover, vent board and their fasteners in normal working condition, a minimum fan maximum diameter of 1/100, and does not less than 1mm
