Continuous duty stepping motors


Electronics CEL

Oriental Motors USA announces the release of the PKE high torque, high efficiency stepping motors that can be driven at continuous duty cycles. The PKE motors are designed to provide maximum torque while creating efficiencies currently not available in the stepper motor market.

Through the use of new technology in the form of new materials, advanced stator and rotor design and construction methods, the PKE stepping motors produce 1.2 to 1.5 times more torque than a conventional stepping motor while significantly reducing the power loss common in stepping motors. Key benefits of the higher efficiency are lower heat generation (78%) by the motor, constant duty operation and up to 40% less power consumption when compared to a conventional stepping motor. CO2 emissions are reduced by up to 15kg less than a conventional model.

(CO2 emissions: Oriental Motor PK245DB 37kg/year →Oriental Motor PKE245DB-L 22kg/year equals a 40% reduction).

Oriental Motors’ new high-efficiency technology used in the PKE stepping motors can lower operating costs by reducing the number of cooling fans that may be required, extend the service life of the equipment by operating cooler and reduce potential problems due to thermal expansion. Increased torque allows for downsizing the motor for space constraint applications.

The PKE stepping motor is available with a motor frame size of 1.65″ sq and three stack lengths of 1.3 in. (PKE243x), 1.54 in. (PKE244x) and 1.85 in. (PKE245x). All of the PKE stepping motors are available with a standard shaft or double shafts and both unipolar and bipolar windings. Output torque from the different models ranges from 34 oz-in for the PKE243A-L unipolar model up to 77.8 oz-in for the PKE245DA-L bipolar motor. Shaft speeds in excess 2000 rpm can be achieved with the PKE Series motors with a 24VDC driver.
