Product Description:

The Sanyo Denki 103H5210-1012 is a standard featured stepper motor that is part of the StepSyn Stepping series. This stepper motor has a bipolar or 2-phase driving method. The stepper motor is designed for high-torque and low-speed industrial applications. This unit operates in open-loop systems that require precise positioning through steps. The 103H5210-1012 operates at a step angle of approximately 1.8 degrees per step with a standing error of +/-0.09 degrees. It has a rated voltage of 5 volts of direct current and a rated current of around 1.8 amperes. And the holding torque is rated approximately at 1.5 newton meters.

The 103H5210-1012 is delivered in a cardboard box, each unit carries a type label that contains information that can be used for the easy identification of the motor upon its delivery. The insulation resistance of the stepper motor is not less than 100 megaohms between winding and frame by direct current for 500 volts at normal temperature and humidity. This stepper motor should be used in an operating environment maintained within an ambient humidity range from 20 percent to 90 per cent. The ambient temperature range should be within -10 degrees Celsius to +50 degrees Celsius. The axial play of this servo motor is about 0.075 millimeters and a maximum load of 4.4 Newtons.

The 103H5210-1012 uses a flange as its mounting type which makes it a suitable industrial option for various applications. The frame size of the stepper motor is comparable to a NEMA 17 format. The unit has class B insulation, which means it is safely operational when under 130 degrees Celsius. As a stepper motor, the unit is best used in short-term operations to prevent overheating.
