Orsatti Electric Motors

Orsatti Electric Motors have been manufactured in Italy since 1967.

As well as the standard range of electric motors, Orsatti manufacture Self Brake in both AC and DC, Dahalander winding, double speed motors and various Flameproof motors.

Single Phase
Single-phase asynchronous OMM motors made of aluminium with one or two condensers (series version) are made of top-quality materials and comply with IEC standards.

All the Orsatti's motors have the following techical finishing on board:

  • Dynamically balanced squirrel-cage rotor made of die-cast aluminium alloy
  • H insulation class of the winding.
  • water protection IP 65.
  • All the motors mounts onboard SKF made in Germany 2RS bearings "life-long" lubricated bearings (25,000 hours).
  • High starting torque.
  • Suitable for continuous S1 operation.
  • Shaft made of C40 steel with centering hole.
  • Best performance.
  • Low noise level.
  • Low vibrations.
  • Light in weight.
  • Recommended for fans, air compressors, circular saws, centrifugal pumps.

Self-Brake AC
The self breaking ORSATTI AC motors are of the enclosed type, with external ventilation and squirrel-cage rotor.

All the Orsatti's motors have the following techical finishings on board:

  • All motors are tropicalized as series production.
  • H insulation class
  • Protection degree: IP 65.
  • Size from 63 to 225.
  • Motors from size 63 to size 132 are made of die-cast aluminium. Motors over 132 are made of cast-iron.
  • OM series AC motors use an alternated current break which makes sharp breaking possible.
  • Room temperature must not exceed 50°C.
  • Series production motors from size 63 to size 225 are equipped with PTC and KLIXON thermal probes at 130° on the three phases.
  • All the motors mounts the SKF bearings 2RS type
  • The frontal and rear bearings are mechanically locked to iproove te axial resistance.
  • The terminal strips are installed on the upper part of the motor and are of the IP 65 class.
  • The epoxy coating is carried out by chamber drying and the standard colour is RAL 5010 blue in conformity to the RoHS regulations.
  • All motors are multi-tension and multi-frequency.
  • S1 continuous operation.
  • These motors have been developed in order to work up to 1000 metres above sea level.
  • Each individual motor is tested when idling and under load.

Dahalander Winding

ORSATTI motors are of the enclosed type, with external ventilation and squirrel-cage rotor.

All the Orsatti's motors have the following techical finishing on board:

  • The motors are tropicalized as series production.
  • H isolation class.
  • Protection degree: IP 65.
  • Size: from 56 to 450.
  • The motors from size 56 to size 132 are made of die-cast aluminium. Sizes over 132 are made of cast-iron.
  • On request, Orsetti is able to produce motors made of aluminium in sizes of 160 and 180.
  • The room temperature must not exceed 50°C.
  • The series production motors from size 56 to size 450 are equipped with PTC and KLIXON thermal probes at 130°C.
  • All the motors are equipped, till the frame 225, with SKF made in Germany bearings 2RS type.
  • Lubricatorsize: from 250 to 450 on SKF Bearings Made in Germany.
  • All the motors from the250 size (excluded the 2 poles ones) mounts at front the roller bearing.
  • The front and rear bearings are mecanically locked on the shaft to improove the axial resistance.
  • Terminal strips are installed on the upper part of the motor and are of the IP 65 class.
  • The epoxy coating is carried out by chamber drying. Its standard colour is RAL 5010 blue.
  • All motors are multi-tension and multi-frequency and have 230/400 Volts, 400/690 Volts and 50/60 Hz
  • S1 continuous operation.
  • The motors have been developed in order to work up to 1000 metres above sea level.
  • Each individual motor is tested when idling and under load.
