Motor offers five programmable speeds plus soft start and stop ramps

Speed setting is by NFC (Near Field Communication) which is contactless and can be done even before the Smart Motor is powered for the first time.

In terms of purchase cost, the Lenze Smart Motor falls between that for a standard motor and one equipped with a variable speed inverter drive. The Smart Motor is designed to run at a fixed speed, but not necessarily at a single speed. Up to five speeds can be programmed and switching is by digital signal.

A closer comparison for cost would be with a two-speed motor and here the Smart Motor scores, particularly with its adjustable soft start and stop ramps, also motor thermal protection. 

The ability to use five preset speeds makes applications such as reversing conveyors simple and easy.  A start signal triggers the soft start ramp up to the first set speed.  As the conveyor approaches the target position a proximity switch signal changes the speed to creep.

At the stop position a signal takes the speed down to the third setting, zero, through the soft stop ramp.  Two further speeds for reverse drive and reverse creep allow return to the original position.  No panel space is needed for reversing contactors or soft starters.

The Lenze Smart Motor is available with helical, shaft-mounted helical and bevel gearboxes for rated output torques from 4 to 650Nm.  Standard options include spring applied holding brakes, blowers and surface coatings for arduous environments.

To speed installation there is a further option of the Phoenix Contact 'QUICKON’ plug connector which cuts out the task of stripping the cable ends.
