High-efficiency 3-phase induction motors for variable speed control 0,75 to 132 kW
Open the catalog to page 1Guaranteed variable speed performance Leroy-Somer is expanding its induction motor offer with a range specially adapted for variable speed. Combined with any type of frequency inverter, the LSMV offers solutions adapted to the industrial environment by producing electrical performance with IE2 efficiency level and mechanical performance by guaranteeing constant torque over a wide operating range without forced ventilation and without derating. Interchangeability The LSMVmotorretainsthe IEC60072-1 dimensions (frame size, mounting distance and shaft diameter) while an induction motor designed...

Open the catalog to page 7LSMV High-efficiency 3-phase induction motors for variable speed control Selection Choice of application type In principle, there are three typical types of load. It is essential to determine the speed range and the application torque (or power) in order to select the drive system: CENTRIFUGAL MACHINES The torque varies as the square of the speed (or cube of the power). The torque required for acceleration is low (about 20% of rated torque). The starting torque is low. * Sizing: depends on the power or torque at maximum speed • Drive selected for normal duty Typical applications:...
Open the catalog to page 8LSMV High-efficiency 3-phase induction motors for variable speed control Selection Choice of number of poles, optional features and brake NUMBER OF POLES The number of poles is one of the main criteria. In fact, as can be seen in the graph opposite, the torque is distributed differently depending on the number of motor poles used. Therefore, for use only at low speed, a 6-pole motor should be chosen. Conversely, for overspeed operation the 2-pole motor should be selected. OPERATING EXTENSIONS Depending on the applications and speed controllers, certain accessories are needed: Forced...
