Product Description:
103H7853-7021 is a high-performance stepper motor. This motor is produced by Sanyo Denki. It is a five-phase motor designed especially for industrial applications. The motor has a double shaft. Its holding torque at 5-phase energization is 1.86 Nm. The rated current is 0.75 Amps per phase. Resistance of the winding is 5.5 Ohms per phase and the inductance is 15 millihenry per phase. The rotor inertia, as per the product documentation, is 0.84 x 10-4 kg m2. Weight of the 103H7853-7021 motor is approximately 1.36 kilograms. Length of the housing is 85.8 millimeters. The main shaft has a diameter of 8 millimeters. Size of the motor flange is 60 millimeters and the dimeter of holes on the flange is 4.5 millimeters. Several drivers can be used with the motor, including PMDPC1S3P0, PMM-MA50064, and PMDPA1C3P20.
Stepping motors move in steps, which are discrete angular movements. Different motors are designed for different step sizes. Operators can order stepping motors with step sizes that match application requirements. Step size of the 103H7853-7021 motor is 0.72 degrees. This is a small step size that is suitable for applications with precise positioning requirements. The motor moves in response to an input pulse from the connected stepper driver. The frequency of pulses determines the number of steps the motor moves each second. Time between movements is determined by the time gap between successive pulses. A big benefit of stepper motors is that they don’t require a position sensor – like an encoder - for position control. This helps to reduce the size of the motor and its cost. Applicable connector for the motor is a Japan solderless terminal. Experienced and qualified staff must install the motor.
