Product Description:
The 103-7506-7041 StepSyn Stepping Motor is manufactured by Sanyo Denki, a high-precision motor specifically designed for high-accuracy motion control applications. This motor is used for applications that demand low vibration, fine step resolution, and uniform torque supply to deliver consistent performance in sophisticated motion systems. This motor has a step angle of 0.45° per step that supports fine movement control and accurate positioning without needing external encoders.
This stepping motor is based on a 5-phase setup, which provides stability, smoother motion, and less vibration than a conventional 2-phase motor. This motor’s rated current of 0.75 A per phase supports effective power utilization while maintaining consistent motor performance under load. The 103-7506-7041 stepping motor features a winding resistance of 4.8 Ω per phase and a winding inductance of 23 mH per phase. This balanced combination is essential in determining the motor's time constant and providing responsive speed and torque characteristics during real-time operations. With a holding torque of 0.91 N·m, the 103-7506-7041 stepping motor helps in maintaining position, which is necessary to avoid any load shift in idle modes.
The rotor inertia of this stepping motor is 0.235 × 10⁻⁴ kg·m². This helps in rapid acceleration and deceleration of the motor with minimal overshoot to enable precise motion profiles. This stepping motor is also equipped with a 60 mm square frame and ensures compatibility with standard mounting hardware and systems, mainly focusing on space efficiency. This motor weighs only 1.1 kg and ensures mechanical rigidity at high speeds while maintaining overall system weight within permissible limits. The 103-7506-7041 stepping motor features a single-shaft output that is easily coupled to mechanical systems or load interfaces without the need for additional modifications.
Frequently Asked Questions about 103-7506-7041:
Q: How does the 5-phase configuration benefit the motor's performance?
A: The 5-phase design reduces resonance and increases step smoothness compared to 2-phase motors. It allows finer control and longer operational life.
Q: Why is the rotor inertia of 0.235 × 10⁻⁴ kg·m² important in 103-7506-7041?
A: It ensures smooth acceleration and deceleration, minimizing positioning errors. This is useful in dynamic load applications.
Q: What is the effect of 23 mH inductance per phase on performance?
A: Higher inductance slows current changes slightly, allowing for more stable motor control. It also reduces overshooting at high speeds.
Q: How does 0.75 A/phase contribute to thermal efficiency?
A: Lower current reduces heat generation and power loss. It enhances compatibility with compact motor drivers.
Q: Why is a 0.45° step angle preferred in the 103-7506-7041 motor?
A: Smaller step angles increase resolution and positioning accuracy. It’s ideal for applications needing fine movement steps.
