Introduction

Electrical drives in their many variations are now in use in everybranch of industry. In most processes, they determine by virtue of their characteristics the economy of production. The three- phase asynchronous motors for low voltage from VEM motors GmbH meet the needs of operators with the regard to all- round versatility, superior performance parameters, environ-mental compatibility and high standard of reliability. VEMmotors are designed for the whole European market and offer?economical performance due to high motor efficiencies?versatility and reduction of stock due to series version in IP 55 degree of protection (higher degrees of protection up to IP 66 on request) ?optional terminal case position right/on the top/left?increased lifetime, reliability and thermal overload capacity by series version insulation class F with thermal reserve (special version insulation class H on request) ?environmental acceptability due to use of a low-noise and bi-directional ventilation system?supply option complying with Eastern European standards ?performance option of a classic IEC/DIN series and on request a progressive one based on the IEC 72 for attach- ment dimensions and frame sizes?attachment options for components as impulse sensors, tacho industrial generators, brakes, speed transducers and forced-venti- lation units for accomplishment with recent control methods
