Product Description:
The 103H7121-0440 stepper motor is a two-phase stepper motor that is designed to create sharp, precise movements known as “Steps” and support the operation of machines that require accuracy in their operation. Typical machines compatible with this stepper motor design include robots, printers, and numerically controlled devices. This motor is produced by Sanyo Denki, and its operation efficiency level is as high as 90 per cent. Compared to other industrial motor unit, this product has a significantly smaller size, making its installation into environments with limited spacing possible. Each step of this industrial motor unit covers an angle of 1.8 degrees; for the complete 360 degrees rotation, the motor has to go through 200 steps. The housing of the 103H7121-0440 carries several certifications that confirm its quality standard; it is a CE listed device and is authorized to be used in Europe, Asia, and North America.
The 103H7121-0440 industrial motor unit has a frame size of 42 millimeters, each phase of its operation consumes an estimated current of 2.8 amperes and a rated voltage of 2.8 volts. The output shaft integrated into the motor unit can produce a torque of 0.58 newton meters. The estimated resistance at each phase of this stepper motor is 1 ohm, while the inductance level is about 1.7milihenry. The operation of this motor is possible in environmental temperatures as low as -10 degrees Celsius and as high as 50 degrees Celsius, also ambient humidity levels should remain between 20 to 90 percent without any risk of water condensation on the motor.
There is no fan attached to the 103H7121-0440 motor unit; it does not produce a high amount of heat during operation and can easily eliminate excess heat via natural convection through its housing surface.
