Product Description:

The 103H5510-70E9 categorized as a SANYO DENKI Stepper Motor which belongs to the StepSyn Stepping Motors family. With an approximate rated voltage of 70V, it operates under low voltage conditions effortlessly. The motor consumes current in the range of 1.0 to 1.5 A which ensures smooth power supply for precise motion control tasks. The motor achieves 1.8 per step with a full rotation step angle limiting error during positioning.

A typical holding torque of 2 to 3 N·m is measured to restrict the load during active work. With no power, residual torque keeps the motor from rotating freely causing unwanted motion. The smooth and steady movement of the motor is achieved with its 2-phase configuration powering the sequence of steps. Autonomy to control current flow is enabled by the phase resistance of about 2–4 ohm which leads to positive responsiveness. The phase inductance permits flow of electric current in the motor windings letting it store energy to power the motor when needed, making it efficient with a measurement typical of 3-8 mH. Standard coupling interfaces are easily compatible as it features a shaft diameter of 8-10 mm.

The 103H5510-70E9 drive utilizes a NEMA 23 type with a foot-mounted configuration that makes fastened implantation in industrial environments effortless. It works dependably in ambient temperatures of about –20C to +60C, allowing the performance to remain stable across a range of environments. The rotor inertia is about 0.00018 kg·m² that allows for acceleration control. Its resonant frequency is approximately 150 Hz, which effectively masks errors made by vibrations. It weighs roughly 0.9 kg, which is helpful for applications that require low masses.
