Incorporating Stepping Motor αSTEP Technology

Incorporating stepping motor αSTEP technology, these models can maintain positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor monitors the rotation speed and amount. When an overload condition is detected, it will instantaneously regain control using the closed loop mode. When an overload condition continues it will output an alarm signal, thereby providing reliability equal to that of a servo motor.

Adopting High Rigidity Guides (Guide type only)

High rigidity guide, utilizing the actuator width at a maximum, is adopted. The high transportable mass and high load moment allow a load to be installed directly on the joint. The joint also has mounting holes for installing a load. The standard type (without a guide) is also available. (For the standard type, a ball screw antispin mechanism must be provided.)

Compact Size by Integrated Design

The hollow rotor and ball screw nut have been integrated. Since no connecting parts are necessary, the compact, high-accuracy mechanism can be used with ease.
