Drive technology for AC and DC

Motor technologyThe KM capacitor motorKM motors are 2- or 4-pole single-phase asynchronousmotors with a main winding and anauxiliary winding. To generate a rotary field, theoperating capacitor, which is switched in serieswith the auxiliary winding, attains a phase shift ofthe main and auxiliary winding. Compared to ACshaded-pole motors, the KM motors feature betterefficiency and a higher start-up torque. Thismotor family includes a total of three differentmodels, one with open housing (IP00), anotherwith semi-open (IP20) and another with closedmotor housing.Facts and figures– Power range (depending on the motor packageheight and number of poles): rated outputup to 300 watts, rated torque up to 70 NcmAn extension of the power range is possiblefor short-time operation (S2)– Nominal voltage/frequency: 230V / 50Hz(Adaptation of the motor winding possible forother voltages and frequencies,e.g. 115V/60Hz)– Direction of rotation: clockwise (also suitablefor counter-clockwise rotation if current flowis changed)– Insulation material class F (VDE/EN)– Bearing system with two ball bearings– Shaft diameter: 8mm (optionally, 10mm or12mm possible)– Drive-side shaft end: 25mm (up to 300mm possible for custom applications)– Mounting position: any (longer service life for horizontal shaft)– Various customer-specific designs available on requestApplication areas– Drive motor for gearbox (including spur, planetary and worm gear units)– Tangential fans (e.g. underfloor convection heating)– Centrifugal and axial fans (e.g. exhaust gas blowers)– Circulation blower for hot air with impeller > 150mm (including ovens and other commercialapplications)– Drive motor for pumps (membrane, gear, submersible circulation and recirculating pumps,condensers and compressors)– Heating engineering in solid fuel burners (including exhaust blowers, screw drives for conveying heating pellets, wood chips or combustion products)– Locking systems and door/gate drives (garage door and roll-down gate drives, etc.)– Polishing and grinding machines– Medical applications (centrifuges, lifting devices such as adjustable operating tables, massagers etc.)– Office equipment (e.g. postage meters, money counting and billing machines, file shredders,paper shredders or copiers)– Conveying and handling equipment (keg pumps, filling systems, single-roll drives for conveyorbelts etc.)– Packaging machines (binding machines, shrink wrap machines, etc.)– Food and food service machines (ice crushers, cutting machines, beverage tapping units,bottle coolers, beverage and sales vending machines etc.)– Various special applications such as film developing machines (such as X-ray film), tankexhaust systemsThe data listed on the following pages pertain to continuous operation S1 at the nominal voltageand frequency.
