Leroy-Somer first introduced its Varmeca motor with integral variable-speed drive in 2000. Now available from 0.25 to 11kW and with shaft heights from 71 to 160mm, the new Varmeca 30’s electronics are potted into a specially formulated compound, designed to resist the effects of vibration and to even-out temperature hot-spots within the drive circuitry. Combined with its IP65 rated, rugged aluminium enclosure, this new design carries forward Varmeca’s historically low failure rate, even when employed in challenging industrial environments.
From the outside, Varmeca looks very much like a traditional, mechanically controlled motor: It features a simple, external speed-control potentiometer with optional start/stop switch, plus an externally controlled unit for start and forward/reverse, with control being provided by a potentiometer or 0-10v analogue input.
A wide number of parameters are accessible via PC or microcontroller, and the Varmeca is also capable of communicating with other devices via a number of popular industrial networking protocols, such as Profibus, DeviceNet and Interbus S.
