Three phase alternating-current motor 4KA

The range of 3 phase alternating-current motors 4KA is the latest version of range of motors of HEM. The motors have the same features including high performance, strong torque, low noise and vibration, nice design and appearance. Power range and installation dimensions are in accordance with IEC standards. The motors’ quality is ensured by the quality management system under the international standard ISO 9001. The motors are widely used for a driven of machines and equipment such as: Metal cutter, pumps, blower, mixing mill, attrition mill. The motor is airtight and cooled by the blower. The protection level of the motor is up to IP56, the working mode is continuous. The steel core of stator and rotor are made of high quality electronical engineering shear steel. Stator winding is copper wires coated with enamel insulation. Class F insulated motors. Stator winding is dried vacuum. The slide bar and rim of the motor are casted by pressure aluminum, high purity aluminum. Whole rotor of the motor is dynamically balanced to ensure smooth, quiet and no noise.  Power range: 0.18 ~ 315KW. Height of axle centre 71~ 355mm. Voltage: 220 / 380V, 380 / 660V. Frequency: 50Hz.

Heat-resistant motor

Hanoi Electro-mechanical Manufacturing Joint Stock Company (HEM) has succeeded in researching, designing and manufacturing asynchronous rotor motors as well as meeting the requirements of testing standards. IEC60034 and IEC60072 installation standards and can especially work in high temperature environments.

H-class heat resistant motors are engineered to ensure long-term operation in high-temperature environments up to 800C, they are made of 2200C insulating material with high heat resistance capability in the long run. Parameters showing the characteristics of this engine are the working mode S1 and the insulation class H. The engine is rated class C or heat stress at 2500C or 3000C for a certain time period from 2 hours to 3 hours is type The engine is made of 2200C insulating material with high heat resistance for 2 to 3 hours. Parameters showing the characteristics of this engine is the working temperature of 2500C to 3000C for 2 hours to 3 hours. Electric motors working in high temperature environments are based on the needs of users and have been certified by the Quatest Test Center I, the qualified engine certification Operated under the above conditions.

Explosion proof motors are cooled by blowers attached to the axles mounted on the rear of the motor or directly by an external blower of blower tube system. These types of motor are used in mines including risks of gas and dust explosion. Flameproof motors are designed assembly dimensions in accordance with TCVN079-0: 2002, TCVN 7079-1: 2002, TCVN 7079-7: 2002, TCVN 7079-9: 2002. – Explosion proof motors’ dimensions are designed in accordance with Vietnamese standard TCVN, IEC34-72, which is very convenient for replacing the same types of motor in mining equipment in Vietnam.
