Product Description:
The 103H7123-0437 is a Stepper Motor that operates in a closed loop mode and maintains a constant rotation speed without slip which makes it useful for applications that require precise speed control. Manufactured by Sanyo Denki it is related to the StepSyn Stepping Motors series.
The 103H7123-0437 Stepper Motor draws 2A of current which suggests more electromagnetic force that leads to higher torque output. It achieves synchronous rotation by using a modified winding configuration and eliminates stepping errors and improves efficiency over a range of loads. The maximum torque the motor can resist without moving when powered but not rotating is 0.83 N.m which makes it suitable for medium load applications. This module has 3.8 mH/phase inductance which is slow and allows it faster step transitions. It is a compact design and suitable for automation, robotics or precision motion control applications as its weight is only 0.65 kg. This model can best work on a 100V AC power supply which suggests it might be used in industrial applications or places where direct AC drive is beneficial. For proper operation, each of its phases requires 2 amperes of current and no extra overhead is needed in the power supply design. When accelerating a given load inertia, it can exert maximum torque of 0.94x10-4 kg·m2 without losing synchronization.
The 103H7123-0437 stepper motor is able to accelerate and decelerate quickly as its rotor inertia is very low equal to 0.21 10-4 kg·m² which allows for fast response times. Its shaft is well aligned with the mounting surface which ensures less vibration and better performance in precision applications. The motor shaft is 0.075mm perpendicular to the mounting surface which helps reduce mechanical misalignment and prevents unnecessary wear on the bearings and couplings.
