Product Description:
103H7121-5010 is a Sanyo Denki stepper motor. It is a two-phase stepper motor from the H series. The motor has a very compact construction with 56 millimeter width. It has a flange for secure mounting and a set of DIP switches for configuration. Basic step size supported by the motor is 1.8 degrees. Stepper motors differ from rotary motors in that they move in steps rather than continuously. A controller connected to the motor delivers pulses which cause the motor to move. The number of pulses determine the number of steps moved. 103H7121-5010 is a stepper motor with a bipolar winding. The main shaft is a single-ended spindle shaft. Voltage rating of the motor is 1.3 Volts. The current per phase is 2 Amps and the resistance per phase is 0.65 Ohms.
Inductance per phase of the motor is 1.9 millihenry. The holding torque is 0.39 Nm. Rotor inertia for the 103H7121-5010 motor is 0.1 x 10-4 kg m2. Weight of the stepper motor is approximately 0.47 kilograms and its connection code is 11. The lead wire as specified in the product documentation is AWG 22. Length of the stepper motor is approximately 41.8 millimeters. Each side of the motor flange measures 56 millimeters. Four mounting holes on the flange allow mounting via screws. The diameter of each mounting hole is 4.5 millimeters. Diameter of the motor shaft is approximately 6.3 millimeters. The aluminum housing provides strong environmental protection. The compact motor requires professional handling. It is a piece of highly specialized industrial equipment that must be installed according to manufacturer instructions. This is important for error-free installation and for reliable long-term motor operation.
