ULTRACT III High performance servo motor Phase Motion Control S.r.l.
Standard shaft technology. To avoid the traditional dichotomy between key–smooth shaft applications, Phase Motion Control releases the new standard shaft in which a key seat is filled with an insert (photo below) and the whole set is ground to shaft tolerance. The shaft is therefore round and ready for clamping with conical hubs (recommended). If a key is required (and the corresponding reduced servo performance is accepted) the insert can be removed and a standard key inserted. All shafts are balanced with the insert so that simple rotating parts (e.g. pulleys, gears) need not to be balanced.
Safety brake: All motors except UL 071040 have an internal cavity where the PM safety brake can be mounted. The brakes are all rare earth permanent magnet type. This new high power density brake operates without brake pads. As a consequence, the problem of pollution of the motor cavity when the brake is operated incorrectly is avoided.
Additional inertia: an extra flywheel can be introduced in the brake cavity to compensate for poor mechanical linkages between the motor and the load.
Single piece extruded frame, smooth, with O-rings on all couplings and IP 65 protection to allow flushing and sterilization in food and chemical applications
Standard circular connectors, turnable 270 degrees, standard high flexibility cables available;
Oversized front bearings improves bearing life by 70%; 28 mm shaft available on request
Peak speed 4000 rpm on standard type
Standard supply: new Heidenhain absolute magnetic encoders, single or multi turn (4096 turns), with electronic nameplate and AUTOSET function (with PMC drives), accuracy 1’, resolution 17 bit/turn, ENDAT full digital serial interface. The motor can also be equipped with sinusoidal optical encoders (Heidenhain ERN 1385, accuracy 20”, interpolated resolution 24 bit/rev, or resolver (accuracy 10’) for low cost, low performance applications.
KTY 84 linear thermal probe for continuous motor temperature sensing
Standard lip seal on shaft accessible from outside for maintenance/replacement
Flange and shaft manufactured to Grade R (reduced tolerance IEC 72)
