ABB YT212001-AF YTEA250-15 Thermocouple output module

Step motors are devices which position loads by operating in discrete increments, or steps, unlike servo motors and other devices that operate at constant speed. The stepping action is accomplished by switching the power to the motor windings so that the motor phases are energized in a specific sequence. Stepper motors are capable of very precise positioning without the use of complicated and expensive feedback devices, although feedback systems may be incorporated into step motor systems if position comparison is desire. Because of the simplified control needs and the freedom from expensive feedback requirements, step motors have become viable alternatives to pneumatic, hydraulic and servo motor systems.

SLO-SYN DC Step 

Motors SLO-SYN DC Step Motors are brushless, permanent magnet motors that have a fullstep increment of 1.8°. they can also be made to operated in increments of 0.9° to 0.0144° when half-stepping or microstepping techniques are employed. Because they are digital devices, SLO-SYN DC Step Motors are easily adapted to different types of control and are ideal for use with microprocessor based systems. SLO-SYN DC Step Motors are offered in a wide range of torque ratings, shaft configurations and frame sizes. Their unique combination of operating features and characteristics have made them the industry standard for industrial automation, scientific applications and office systems.

Construction 

SLO-SYN Step Motors have permanent magnet rotors and eight-pole stators. They do not have brushes, ratchets or detents to wear out and they use shielded, lubricated-forlife ball bearings to insure maximum reliability and long life. Tests indicate a typical minimum life of five years. The motors are totally enclosed , but are not sealed against direct splash of water, oil or other liquids. When the operating environment includes direct splash of water, oil, cutting fluids, etc., the motors should be protected from exposure to the fluids. NOTE: M112-FJ and M112-FF motor models are sealed against ingress of liquids and dust per I.E.C.IP-56.
