Lower-Loss Technology for a Stepping Motor
The demand for stepping motors with high efficiency and low losses has been increasing, although the demand had been previously focused on high torque. Also, the selection of the most suitable grade of lamination for improvement in fastening of the laminated cores has reduced losses significantly at their peak, when compared to conventional stepping motors. Lowering the losses of the motor has enabled continuous operation that was previously impossible. An expansion of the stepping motorâ™s usage into applications where another motor has been used for continuous operation and other usesâ”due to the heat generation problemâ”can now be pursued. In addition, these motors are very effective for energy saving. This paper explains the technology used for lowering the iron losses of the stepping motor.
Historic Danish Theatre Gets a Facelift
