Overview of Stepper Motors Stepper motors enable accurate positioning operation with ease. They are used in various types of equipment for accurate rotation angle and speed control using pulse signals. 5-Phase Stepper Motors (500 steps) 2-Phase Stepper Motors (200 steps) $Accurate Positioning in Fine Steps $ A stepper motor rotates with a fixed step angle, just like the second hand of a clock. This angle is called "basic step angle." Oriental Motor offers 5-phase stepper motors with a basic step angle of 0.72˚ and 2-phase stepper motors with a basic step angle of 1.8˚. $Easy Control with Pulse...

Stepper Motors $Generating High Torque with a Compact Body $ Stepper motors generate high torque with a compact body. These features provide excellent acceleration and response characteristics, which in turn makes these motors well-suited for torque-demanding applications where the motor must be started and stopped frequently. To meet the need for greater torque at low speed, Oriental Motor also has geared motors combining compact design and high torque. ◇$Frequent Starting/Stopping is Possible ◇Speed – Torque Characteristics [Motor frame size 60 mm (2�36 in�)] 1.2 Torque [oz-in] Motor & Driver...

A-6 Overview ■Motor Types ■ Stepper motors come in several different types including the standard type, electromagnetic brake type and various geared types. The availability of such a wide selection means that you can choose an optimal type according to the function and performance required in your specific application. Typical examples are introduced below. Standard Type A basic model that is easy to use and designed with a balanced set of functions and characteristics. Electromagnetic Brake Type These motors incorporate a non-excitation type electromagnetic brake. When the power is accidentally...

Stepper Motors ■Driver Types Built-in Controller Type With this type, the operating data is set in the driver, and is then selected and executed from the host system. Host system connection and control are performed with any of the following: I/O, Modbus (RTU), RS-485 communication, or FA network. By using a network converter (sold separately), CC-link, MECHATROLINK or EtherCAT communication is possible. Setting Operating Data and Changing Parameters Basic Setting (Factory setting) When Controlling from Computer or Touch Screen CPU Positioning Module Not Power Supply I/O Required ●Setting using...

Overview ■Advantages of Geared Motors Using geared motors bring many advantages, such as speed reduction, high torque and high resolution. • The Motor Can Drive a Large Inertial Load If compared with a standard motor, the geared motors can drive larger inertial loads because its permissible load moment of inertia increases with the square of the gear ratio. This means that larger inertial loads can be driven with geared motors. O Comparison of Load Moment of Inertia • Improved Damping Characteristic at Start and Stop If the inertial load is large or acceleration/ deceleration time is short, a...

Stepper Motors $Downsizing $ PS Geared Motor PKE564AC-PS25 Weight: 1.4 kg (3.1 lb.), TH = 8 N·m (70 lb-in) 60 mm (2.36 in.) If comparing the standard motor and the geared motor, which have similar maximum holding torque, the frame size of the geared motor is smaller than the standard motor. Geared motors are effective when the equipment must be kept small and light. Standard Motor PKE5913AC Weight: 4.1 kg (9 lb.), TH = 6.3 N·m (55 lb-in) Overview ✽ TH means “Maximum Holding Torque” $Surface Installation of Load (Harmonic geared type) $ The harmonic geared type permits installation of a load directly...

Stepper Motors The characteristics diagram below shows the relationship between the speed and torque when a stepper motor is driven. The required speed and torque is always used when selecting a stepper motor. On the graph of characteristics, the horizontal axis expresses the speed at the motor output shaft, while the vertical axis expresses the torque. The speed - torque characteristics are determined by the motor and driver, so they are greatly affected by the type of driver being used. ©Maximum Holding Torque This is the maximum holding torque (holding force) the stepper motor has when power...
