Permanent Excited Reluctance Motors

Watercooled electric motors can be realised in any possible mechanical and electrical customised version. They can be realised in vacuum tight version for fan drive on thermal treating oven.

Stainless steel motors are used in sanitary areas such as in the food and beverage industry or in the pharmaceutical sector. The smooth surface of the motors is designed in accordance to the EHEDG guidelines to avoid dirt accumulation. To ensure longlasting and lowmaintenance operation, critical components such as bearings and seals are specially tested. Due to an extensive stock of motor components, standard and special motors can be delivered in a short time. Here are some of the common specifications Sizes 63160 0.18 to 22 kW 2 8 pole windings Special windings Enclosure IP66, optional IP69K Special shaft ends Terminal box or cables

Unexcited synchronous motors Reluctance motors are used in textile machinery as drive for godets and spinning pumps. In general they are used in inverter application as single drive or group drive. Reluctance motors can be realised for any voltage/frequency ratio U/f. Speed >15.000min1 is possible. A great no. of variations concerning special shaft, flange bearing and housing is available. Reluctance motors are available for hazardous locations in flameproof design.

Electric motors for high speed application (approx. 6.000 up to approx. 30.000min1) need to be designed with special concern for bearings, greasing and ventilation.
