Tamagawa OIH Series TS3617N503 Hollow Shaft Incremental Encoder 48mm for Industrial Automation

Simple positioning control through high torque and sensorless motors. Comprehensive lineup designed for various applications.

Step motor rotational speed is defined by pulse rate, and rotational angle is determined by pulse quantity. These digital signals enable open loop control without requiring feedback structure. The unit step angle is defined by the mechanical structure of rotor and stator components.

• Open Loop Control: Rotation angle is proportional to input pulse signals, and rotational speed is proportional to input pulse rate, enabling open loop operation.
• Compact & Lightweight: Lineup includes 20mm flange size and 50g weight options for both 2-phase and 5-phase motor types, facilitating device size and weight reduction.
• High Torque Performance: Features holding torque for stationary positioning during excitation and self-holding force (detent torque) in non-excitation state, providing high torque control capabilities.
• Cost-Effective: No sensor requirement for feedback and simplified drive system make step motors more economical than servo motors.

Step motors utilize a cylindrical rotor with permanent magnet and toothed outer periphery rotating within a corresponding toothed stator iron core. External current supplied to stator coils creates electromagnetism that interacts with rotor magnetic force to produce rotation.

Step motor operation requires excitation of windings through sequential DC voltage and current application. Minimum components include oscillator, driver, and DC power supply. Optional optical encoders or sensors can enhance angle accuracy and damping characteristics.

• Full-step Driving: Operation at basic step angle resolution
• Half-step Driving: Operation at half of basic step angle
• Micro-step Driving: Operation at 1/N of basic step angle with electrical interpolation through controlled winding current for smooth rotation
