High-efficiency Closed Loop Stepping Motor and Driver Package
AR Series
The AR Series substantially reduces heat generation from the motor through use of high-efficiency technology. With the AR Series, you can take advantage of the beneficial features of the stepping motor to perform quick positioning operations over a short distance repeatedly without worrying about the drive duty.
Already a Star in Japan!
The AR Series, High Efficiency, Closed-Loop Stepping Motor featuring lower heat generation has received the Ministry of Economic, Trade and Industry (METI) Minister Award, at the 29th Excellent Energy-saving Devices Awards, held by The Japan Machinery Federation (JMF).
The annual event, held since 1980, recognizes business corporations' efforts to reduce power consumption through development and practical use of energy-saving devices. METI Awards are presented to the most excellent energy-saving products which were developed and put to practical use in last 5 years.
Use of high efficiency technology, AR Series reduced power consumption by up to 100W* and efficiency was improved by up to 20% for AR Series compared to its predecessor. By lowering the losses of the motor, continuous operation has been made possible.
*It was measured based on AR69AA-1 by Oriental Motor Co., Ltd.
Adopting Oriental Motor's Original Closed Loop Control
Adopting the closed loop control, the AR Series does not lose synchronism even when subjected to abrupt load fluctuation or acceleration. A rotor position detection sensor constantly monitors the motor movement. If synchronism is about to be lost, the closed loop control is activated, so there is no need to worry about loss of steps. When the successive overload is given, AR Series is as high as that of a servo motor.
Lower Heat Generation
The AR Series adopts high-efficiency technology to achieve a significant reduction in the amount of heat generated from the motor.
Energy-Saving
Power Consumption: 40% less than a conventional model (also by Oriental Motor)
Improved Angle Accuracy & High Response
The AR Series adopts improved current control technology to improve the stop position accuracy of the motor. The result is a greater positioning accuracy. (See the graph on top.)
Also, the motor operates synchronously with pulse commands to achive high response. There is no delay in operation following a pulse command.
