AC Input stepper motor drivers offer superior torque characteristics over a wide speed range, from low to high speeds, providing a large speed ratio. Supports Closed Loop control without gain tuning or hunting problems when used with the AlphaStep AZ Series (absolute mechanical encoder) motor or the AlphaStep AR Series (built-in resolver) motor for superior control. The RKII Series (open loop) is ideal for demanding applications where feedback is not required.

Stepper motor drivers are specifically designed to drive stepper motors, which are capable of continuous rotation with precise position control, even without a feedback system.Our stepper motor drivers offer adjustable current control and multiple step resolutions, and they feature built-in translators that allow a stepper motor to be controlled with simple step and direction inputs. A stepper motor is driven by a DC voltage applied through a driver. In Oriental Motor's 24 VDC input motor and driver systems, 24 VDC is applied to the motor. In the 100-115 VAC motor and driver systems, the input is rectified to DC and then approximately 140 VDC is applied to the motor (certain products are exceptions to this.). Each stepper motor and driver combines a stepper motor selected from various types, with a dedicated driver. Drivers that operate in the pulse input mode and built-in controller mode are available. You can select a desired combination according to the required operation system.

All AC Input stepper motor drivers feature Oriental Motor's advance microstepping (Smooth Drive) control. These drivers are available in pulse input or stored data (Network) types through our FLEX product group and offer electromagnetic brake control for vertical operations.

Utilize the AlphaStep Closed Loop drivers on all our Actuator based products as a common platform to simplify wiring, improve machine performance and Networking. Fms flight simulator windows 10.

Types of Stepper Motor Drivers

Drivers that operate in the pulse input mode and built-in controller mode are available. You can select a desired combination according to the required operation system.

Pulse Input Drivers

The stepper motor can be controlled using a pulse generator provided by the user. Operation data is input to the pulse generator beforehand. The user then selects the operation data on the host programmable controller, then inputs the operation command.

Built-in Controller (Stored Data or Stored Program) Type Drivers

The built-in pulse generation function allows the motor to be driven via a directly connected personal computer or programmable controller. Since no separate pulse generator is required, drivers of this type save space and simplify wiring.

Difference Between AC Input and DC Input Characteristics

Stepper Motor Driver Diy

A stepper motor is driven by a DC voltage applied through a driver. In Oriental Motor's 24 VDC input motor and driver systems, 24 VDC is applied to the motor. In the 100-115 VAC motor and driver systems, the input is rectified to DC and then approximately 140 VDC is applied to the motor (certain products are exceptions to this.)

This difference in voltage applied to the motors appears as a difference in torque characteristics at high speeds. This is due to the fact that the higher the applied voltage is, the faster the current rise through the motor windings will be, facilitating the application of rated current at higher speeds. Thus, the AC input motor and driver system has superior torque characteristics over a wide speed range, from low to high speeds, offering a large speed ratio.

It is recommended that AC input motor and driver systems, which are compatible over a wider range of operating conditions than DC input systems, be considered for your application.
