Description
These are squirrel-cage motors with NEMA Design A, B, C and D characteristics, including versions adjustable for an inverter. Speeds are 3600, 1800, 1200, 900, 600 and 300 rpm, the frequency is 60 Hz, up to 133 Hz from the inverter. Frame sizes are the manufacturer's own, from 800 to 1400LL, with special housings on request. The housing and end shields are made of cast aluminium with smooth surfaces and an enamel coating. The core is electrical steel M-19, M-36 or M-45, and the insulation is class B, F, H with vacuum impregnation. The short housing makes Waferthin the basis for torque motors, hydraulic pump units and motors with a brake, as well as multi-motor drives. Options cover encoders, resolvers, temperature sensors, brakes, vibration mounts and vibration sensors.
How to choose
This format is used where installation space is limited and a standard motor of normal length does not fit without reworking the frame, for example in machine tools, textile machines and lifting and conveying equipment. The upper limit of 75 hp covers most such tasks, and for higher powers up to 350 hp look at SS-100 with inverter supply. If speeds up to 30 000 rpm are needed, there is High Speed Air Cooled.
