Product Description:

103H6703-50XE43 is a 2-phase synchronous motor tailored for industrial uses, offering consistent rotation speed even when dealing with varying loads. This motor uses commercial AC power directly, removing the need for extra driving parts, so system integration is easier. Due to its design, the core function of this motor is for constant rotation purposes to maintain exact operations through different conditions and environments. The design also allows for stable transferring, which works as an alternative to a stepping motor’s wire wound.

The 103H6703-50XE43 operates effectively across an ambient temperature range of -10C to +50C, it is ideal for use in controlled environments. During testing, it can handle 50/60Hz, 1KV AC for 1 minute with limited leakage. Operation requires an environment of ambient relative humidity between 20% and 95% (without condensation), it should prevent any disruption on its usage. In addition, the axial play of the motor is controlled not to exceed 0.075 mm, therefore promoting mechanical stability and accuracy so the operations are kept without mistakes or issues. The motor ensures ultra low speed rotation and features high torque output to provide reliable power at lower speed.

The 103H6703-50XE43 StepSyn stepping motor is applicable for several applications, which includes uses in conveyor drives, printers, and cryopump ultimate freezers, as well as general industrial applications. Its design keeps a steady rotation by being proportional to the uses of AC power frequency that drives it. The motor's insulation resistance remains strong at not less than 100 MΩ between its winding and frame when checked with DC 500V, confirming safety and prolonged durability by avoiding potential issues when operating. The internal parts are temperature controlled, so even after running continuously, the winding temperature rise stays below 80K under normal use.
