    Self-braking motors

    Autofrenante Trifase + Doppia Polarità

    Self-braking motors:

    • Direct current brake (DC)
    • Alternating current brake (AC)
    • “DC’s brake”: Direct current, parking brake

    Information:

    These use spring-pressure brakes, firmly spliced onto a cast iron shield at the back of the motor. In the S line, the shield may be aluminum. Powered by direct current or alternating current, with negative action (positive upon request). The braking action appears in the absence of power supply to the brake coil; these are therefore negative brakes except positive brake (Tab. 20). The insulation class of these brakes is “Class F”. For single-phase, three-phase and dual-polarity motors, these faithfully follow the specifications already illustrated in this catalogue from a mechanical and electrical standpoint, with the exception of axial dimensions which increase due to the presence of the brake. The lining of our brakes is asbestos-free, per the most recent EEC Directives in terms of Workplace Hygiene and Safety. All brake assemblies are protected against atmospheric aggression by painting and/or heat galvanizing. The parts most subject to wear are treated in special atmospheres that provide considerable wear resistance to the parts.

    Dual-polarity

    Dual-polaritymotori-elettrici-monofase1

    • Size: from IEC 50 to IEC 100
    • Power range: from 0.37/0.25 KW to 1.8/1.5KW
    • Poles: 2 -4
    • Configurations: B3 – B5 – B14 (B3/B5 – B3/B14)
    • Voltage: Volt 230-50H
    • Variant: self-braking, power cooling

    Specifications:

    Engines high technology derived from our unique experience and technology. You get high power outputs, a 30% relative standard motors catalogue on equal all other conditions. In some cases, using only one capacitor for the two speeds, with consequent circuit simplification. Silent, reliable, high performance, it is a further evolution of the single-phase motor, have inrush current in% and drive torque% similar to standard motors.

        Each engine is tested with electronic instruments calibrated and with ISO 9001 certification , which detect the electrical and mechanical properties to determine the rated performance. It is also subjected to tests of reliability and durability before being produced.

        Finally, a further guarantee of customer, over the entire production, is carried out a final inspection assembly. In case of particular requests we can offer specific applications.
