High Accuracy
In general, stopping accuracy tends to be lower during microstep operation than full step operation and this effect is more noticeable in a 1.8° motor. In this situation, using a 0.72°/0.36° stepper motor along with a CVD 5-phase driver enables a higher positioning accuracy.
Stopping Accuracy:
- 0.72° = ±0.05° (±3 arcmin)
- 0.36° = ±0.034° (±2 arcmin)
Low Vibration and Low Noise
Because the basic step angle is small at 0.72° (0.36° for high-resolution type), the vibrations and noise are lower than the 2-phase stepper motor with a basic step angle of 1.8°. Also, vibrations and noise can be further reduced with the use of a 5-phase stepper motor and CVD 5-phase driver..
Direct Replace for 2-Phase Motors
Our 5-phase stepper motors are now available in multiple frame sizes to allow for direct replacement of standard 2-phase motors allowing for increased resolution and lower vibration on your application.
Utilizing Hybrid Stepper Motor Technology
A hybrid stepper motor is a combination of the variable reluctance and permanent magnet type motors. The rotor of a hybrid stepper motor is axially magnetized like a permanent magnet stepper motor, and the stator is electromagnetically energized like a variable reluctance stepper motor. Both the stator and rotor are multi-toothed.
A hybrid stepper motor has an axially magnetized rotor, meaning one end is magnetized as a north pole, and the other end a south pole. Toothed rotor cups are placed on each end of the magnet, and the cups are offset by half of a tooth pitch.
High-Resolution Type Stepper Motors (0.36°)
- 1.10 in. (28 mm)
- 1.65 in. (42 mm)
- 2.36 in. (60 mm)
High-Resolution
The 0.36° high-torque type stepper motors provide 1000 steps per revolution by having 100 teeth on the rotor. This contributes to the highest resolution and lowest vibration.
Lowest Vibration
The lowest vibration is achieved using the smallest basic step angle of 0.36°.
Generates Higher Torque
The high-torque stepper motor generates approx. 1.2 to 1.5 times the torque achieved by the standard motor stepper motor.
Stop Position Accuracy of 2 Arc Minutes (No Load)
The 0.36° high-torque type stepper motor is designed with a stop position accuracy of 2 arc minutes (0.034°) [standard type: 3 arc minutes (0.05°)]. The reduced error helps improve the positioning accuracy.

Because of its high accuracy, this type has the same level of accuracy when compared to our tapered (TH) type without the added cost of tapering.

Magnetic Encoders
Magnetic encoders do not use a light emitter or a light receiver but still use a code wheel and a sensor. Instead of slits, the code wheel has alternating north and south pole magnets on the outer edge of the code wheel. The magnetic sensor senses changes in magnetic polarity when the poles pass by. The end result is the same as the output circuit outputs pulses to a PLC or HMI. Since there's no need to power the light emitter and receiver, the magnetic encoder uses less power than an optical encoder.
Magnetic encoders are more robust than optical encoders in the sense that they can operate better in humid, dusty, or dirty environments. However, magnetic encoders may not work well in an environment with magnetic interference. Magnetic encoders are also offered in rotary, linear, incremental, and absolute types. To enable a magnetic encoder to track absolute positions, multiple magnetic disks are necessary.
Detecting for Errors
An incremental encoder works by providing an A and B pulse output. The counting is done through external electronics. Here, the encoder counter is compared to the commanded position counter (third party electronics). The point where the counting begins depends on the counter in the external electronics and not on the position of the encoder.
Capable of More Accurate System Control
Monitoring the current position and detecting positional errors is possible.
By using a detection pulse guaranteed at ±0.36°, more accurate
system control is possible.
Capable of Highly Reproducible Return-to-Home
The Z-phase signal is output using the excitation home (stable point), so the home sensor (the sensor that detects the home within one rotation, installed on the motor shaft) can be used instead.
It is also easier for the Z-phase output signal and TIM output signal✽ to be used together, increasing the reproducibility of return-to-home.
A rotary encoder is an electro-mechanical device that converts the angular position of a shaft to an analog or digital code. There are two main types: absolute and incremental. Oriental Motor offers incremental types (Line Driver or Voltage (TTL equivalent)) as a standard product for our stepper motors. For an absolute encoder solution, use the AZ Series. For other standard product encoder offerings and motors that correct themselves, contact technical support for assistance.
An incremental encoder provides the incremental change in position of the encoder to the counting electronics. Stepper motors with incremental encoders make it possible to monitor the present position and detect for errors. Position monitoring can be used to detect the position of the motor. For instance, to confirm normal operations, compare commanded position to the actual position.
3-Channel Encoders
Use the Index signal for the return-to-home operation. By using the Index signal, the return-to-home point will be detected with higher accuracy than single use of the return-to-home sensor. The index channel is an optional output channel which provides one pulse per revolution.
Line Driver Output Type
The Line Driver output offers excellent noise resistance because of the differential output and is capable of longer wiring distance compared to the voltage output.
