Description
In its Special Motors series the manufacturer produces several types of low-speed, high-torque synchronous motors for heavy gearless drives in the metallurgy and mining industries. All of them run from medium-voltage frequency converters and are designed for high torque, reliable operation under heavy loads and long service life. HV RM rolling is a motor for the main drives of rolling mills: synchronous with a laminated cylindrical rotor (standard) or, optionally, asynchronous. Power is 0.5–16.5 MW, torque up to 2460 kN·m, the speed range is 20–1500 rpm with a typical base speed of 50–900 rpm, and the motor has 4–24 poles. HV SM ring is a ring synchronous motor up to 38.8 MW with up to 96 poles and a converter voltage typically up to 4 kV; the rotor of the ring motor is mounted directly on the mill drum, forming a gearless drive for large ball and semi-autogenous mills. HV CW torque is a synchronous torque motor with power of 1–17 MW, torque of 250–2000 kN·m, speed up to 80 rpm and 12–24 poles. In the conveyor version it forms a gearless drive of belt conveyors; in the version for mine hoists the motor is flanged onto the hoist shaft (standard) or built into the drum (optional, up to 32 poles). The gearless design eliminates the gearbox as a source of failures, losses and maintenance. The motors are used together with SL150 (cycloconverters), SM150 and GM150 converters. Applications are rolling mills in ferrous and non-ferrous metallurgy, ore grinding mills of concentrating plants, main and inclined conveyors at quarries, and mine hoists. High-voltage motors are produced at plants in Nuremberg and Berlin (Germany), Drasov (Czechia), Tianjin (China), Mumbai (India) and Norwood (USA), and more than 2000 service specialists worldwide provide service.
