Single phase, single speed, air over, PSC induction motors for centrifugal blowers for fan coil units. With additional autotransformer a range of up to 7 speeds is attainable. Shafts have 10 mm diameter to reduce friction losses at start-up; they are supported by self-aligning sleeve bearings kept in place by special spiral springs which guarantee optimum alignment between bearings and shaft; the lubricant reserve of the bearings guarantees long, maintenance free, silent operation. Fan wheels having 12,7 mm diameter hubs can be mounted by using suitable adapting sleeves. Motors are available either with single shaft or double shaft and are supplied with rubber vibration absorbing rings for mounting on supporting cradle.
Other characteristics are:

-Self resetting thermal protectors
-Closed construction with IP 43 protection level
-C50 steel shafts with low axial end play
-Class B insulation.
-Standard power connections with single pole wires (standard length 200 mm ) with 6.35 mm female fast-on connectors.
Other lengths and connectors are available on request.
Only standard models are illustrated. Upon request motors may be supplied with other shaft diameters or lengths or foreseen for operation at different voltages / frequencies
