BR series gear reduction three-phase asynchronous motors are designed and manufactured according to JB/T6447-92 standards, and are quality products that meet IEC standards. It is composed of a driving motor coupled with a gear reduction device. It has the characteristics of compact structure, small size, light weight, low noise, small vibration, and high efficiency. It is an ideal low-speed power source. Widely used in metallurgy, mining, light industry, chemical industry, steel, cement, textile, printing and dyeing, sugar, food, rubber, medicine, construction, lifting transportation, agricultural machinery and other industries; the production can be used for supporting and maintenance of imported equipment. According to the needs of users, it can still be equipped with various types of motors such as multi-speed, high-efficiency, and DC, and can be equipped with DC electromagnetic brakes or one-way stoppers and various encoders according to user requirements. The degree of protection varies with the matching motor, which can be IP44 or IP54, etc., and the cooling method is ICO141. The parameters of the gears of this series of deceleration motors have been optimized and designed. They are forged with high-quality alloy steel, made of gears and given strict heat treatment. The gears are ground by the worm grinding wheel gear grinding machine of Swiss REISHAUER company, and the precision reaches GB/T10095.1-2001. Level 5. The machine base is made of high-strength cast iron, and has two structures of bottom corner and flange (bottom corner + flange structure is available). The efficiency of the deceleration device, when installed in B3 or B5, the single-stage deceleration transmission is not less than 96%, the two-stage deceleration transmission is not less than 94%, the three-stage deceleration transmission is not less than 92%, and the insulation grade of the motor is Class B. The winding and insulation have good electrical, mechanical, moisture-proof performance and thermal stability.
