Product Description:

The 103H3215-5270 is a Stepping Motor which is a precise and low torque motor commonly used in Industrial automation systems. With a relatively low weight and compact size this StepSyn Stepping Motors series model is designed by Sanyo Denki for efficient operation in tight spaces.

The 103H3215-5270 StepSyn Stepping Motor comes with a lead thermal wire of SPH-002T-P0.5S which is a terminal used for the connection with the power sources. It comes from a manufacturer and ensures compatibility with certain wiring harnesses. The size of the mounting holes in this model is 4-M2.6 P0.45 that ensures that the motor can be properly installed on a mounting surface, with the given dimensions that shows the hole size, thread type and pitch. The step angle is 1.8°/step which is the angle the motor's shaft moves per step. This specification means the motor moves 1.8° with each step, which is typical for many stepping motors and gives the motor a high degree of accuracy in its positioning. The amount of torque the motor can exert when it is stationary and energized is 0.062 N·m .

This 103H3215-5270 stepSyn stepping motor can hold this much torque when both phases are energized, which is important for holding loads in position. The connector used for wiring the motor to its controller or driver is JST PHR-6 which is a specific type of connector that guarantees proper electrical connections. The mounting depth of this motor is 28 mm square which shows how deep the motor body is for installation and helps determine how the motor fits into a given space. The overall physical dimensions of the motor is 31±0.8 x 20±0.5 x 28±0.5 mm that includes acceptable tolerances of ±0.8 mm and 0.5 mm.

Frequently Asked Questions about 103H3215-5270:

Q: How does the 1.8° step angle of the 103H3215-5270 StepSyn motor improve performance?

A: The 1.8° step angle allows for fine resolution, enabling precise control in positioning applications. It improves accuracy, making it ideal for sensitive tasks.

Q: Why is the low rotor inertia of the 103H3215-5270 beneficial?

A: The low rotor inertia ensures quick response to changes in speed, which is crucial for high-performance applications requiring rapid acceleration and deceleration.

Q: How does the holding torque of 0.062 N·m benefit the 103H3215-5270 motor?

A: Holding torque prevents the motor from moving when stationary, allowing it to maintain a fixed position under load, enhancing stability in automation systems.

Q: Why is the wiring resistance of 2.6 Ω/phase significant in the 103H3215-5270 motor?

A: Lower wiring resistance reduces energy loss and heat generation, which enhances the motor’s efficiency and longevity, especially under continuous operation.

Q: What does the 0.8 mH wiring inductance of the 103H3215-5270 motor affect?

A: The inductance impacts the motor's response time to current changes. A balanced inductance helps ensure smooth and efficient motion control.
