αSTEP AR-Serie
Schrittmotoren der AR-Serie mit geschlossenem Regelkreis
Die Schrittmotoren der αSTEP AR-Serie bieten einen hohen Wirkungsgrad, geringe Vibrationen und einen kontinuierlichen Betrieb mit der Sicherheit einer geschlossenen Regelkreisfunktion ohne Schwingungen oder Verstärkungsanpassung. Das System ist mit einem integrierten Controller oder einem Impulseingangs-Treiber erhältlich und reduziert durch den Einsatz hocheffizienter Technologie die Wärmeentwicklung des Schrittmotors erheblich. Die αSTEP AR-Serie erreicht außerdem einen um bis zu 40 % geringeren Stromverbrauch, eine verbesserte Winkelgenauigkeit und ist in der Lage, Lasten mit hoher Trägheit anzutreiben. Zur Verwendung mit αSTEP AR-Serien-Treibern.

High Reliability with Closed Loop Control
The αSTEP AR Series uses Oriental Motor's closed loop control to maintain positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor monitors the rotation. When an overload condition is detected, the αSTEP AR Series will instantaneously regain control using the closed loop mode. When an overload condition continues, the αSTEP AR Series will output an alarm signal, thereby providing reliability equal to that of a servo motor.
Continuous Operation
The αSTEP AR Series can be operated at high duty cycles allowing the stepper motor to run continuously.
Note: If the stepper motor is operated continuously, a heat sink of a capacity at least equivalent to an aluminum plate with a size of 250 x 250mm*, 6mm thick is required.
*For AC input, 100 x 100mm for DC input type.
Energy-Saving
Power consumption: up to 40% less than our conventional models.
CO2 emission: up to 40% less than our conventional model (assuming operation at a duty of 40%).
Lower Heat Generation
The αSTEP AR Series utilizes high-efficiency technology to achieve a significant reduction in the amount of heat generated from the stepper motor.
The stepper motor generates significantly less heat than the conventional model as seen in the thermography results below.
The graph below shows the difference in temperature of the stepper motor case over the same period of time under the same operating conditions.
Low Vibration
In addition to the microstep drive system, the AR Series also uses the smooth drive function to allow for smoother motion. The smooth drive function automatically implements microstep drive based on the same travel amount and speed used in the full-step mode, without changing the pulse input settings.
Improved Angle Accuracy
The αSTEP AR Series uses improved current control technology to improve the stop position accuracy of the stepper motor. The result is greater position accuracy.
AR66AC-3: ±3 arc minutes
Conventional Model: ±5 arc minutes
Performance of a Stepper Motor
The αSTEP AR Series maintains all of the benefits of a stepper motor.
High Response
The stepper motor operates synchronously with pulse commands to achieve high response. There's no delay in operation following a pulse command.
Capable of Driving Large Inertia Loads
Compared to a servo motor of the same frame size, a larger inertial load can be driven regardless of speed conditions.
No Hunting / No Tuning
Because it uses a stepper motor, the αSTEP AR Series does not hunt when stopped. Accordingly, the αSTEP AR Series is ideal for applications where the equipment uses a belt-drive mechanism or otherwise has low rigidity and you don't want it to vibrate when stopping.
With the AR Series, you can perform positioning quickly after a load change, etc., without adjusting any gains.
Motor Protection Degree: IP65*
The stepper motor complies with the requirements of protection degree IP65* (except for the motor mounting surface and connectors). This means that the enclosure prevents intrusion of dust that can otherwise inhibit normal operation.
*Excluding 1.10 in. (20 mm) and double shaft models.
Sensorless Homing
The αSTEP AR series features extended functions not normally offered on conventional stepper motors. Using the TLC output on the AR, we can sense a preset torque setting range or perform a torque control function.
