Description
Traction motors are the basis of electric train drives, which the company has designed and manufactured since its founding in 1918. The machines are designed for heavy railway conditions: vibration, temperature variations, dust and long-term operation. The motors are highly efficient and highly utilized, which allows their dimensions and mass to be reduced and energy consumption to be lowered; they are manufactured in ratings from 50 to 400 kW. Life-cycle cost is reduced through optimized service-life calculation and ease of maintenance: an intermediate bearing lubrication system is used, and the design allows the bearings to be replaced without disassembling the motor, which extends the overhaul interval. Three cooling versions are produced. Self-ventilated open-type motors have high cooling efficiency. Totally enclosed motors with internal and external fans are dust-proof, low-noise and need almost no maintenance thanks to the sealed design. For high-speed trains, frameless motors with forced air cooling are used. All these versions are mounted on the bogie and operate with a parallel cardan drive with a solid shaft. Examples from the catalogue: a motor for high-speed lines fed from a 20 or 25 kV AC overhead line, 300 kW continuous power at a mass of 431 kg; a totally enclosed motor for urban lines of 1500 V DC, 190 kW hourly power, 625 kg; a self-ventilated motor for an ultra-low-floor tram (600 V DC), 50 kW hourly power, 280 kg, diameter 305 mm. The motors are used on Shinkansen trains, suburban electric trains and metro, low-floor trams and automated people mover (APM) systems; The equipment operates, in particular, on E7, E8, N700S, E131, 227 trains and many private lines in Japan. The company also supplies VVVF traction inverters and gearboxes matched to the motors, that is, a complete traction drive. For Ukraine this is an analog of traction motors of electric trains and trams produced in the post-Soviet area.
