GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Efficiency of motors New efficiency classes for the low-voltage three-phase motors (IE = International Efficiency). Along with the international discussion on energy efficiency a worldwide harmonized energy efficiency standard classification system has been established for low-voltage three-phase asynchronous motors. For many years low-voltage three-phase motors in the European Union have been sold in three efficiency classes EFF3, EFF2 and EFF1. Aside from this, many different efficiency classification systems have been introduced and well-proven in many...

The Commission Regulation (EC) No 2019/1781 & 2021/341 describes efficiency requirements coming into force on 2021-07-01 and 2023-07-01. The required efficiency class of three phase induction motors has to be as follows: Explosion protected motors except motors dedicated for underground mining Required efficiency class of three phase induction motors General purpose motors Cantoni Group pursuing a policy of continuous development of its products, back in the past already took actions to extend offer of high efficiency motors including also explosion-proof motors – we are ready for the new requirements....

Insulation classification The insulation system of an electric motor is determined by a given insulation class on the basis of its thermal resistance. This thermal resistance should be guaranteed by the entire set of electric insulating materials used in the motor insulating system. Thermal resistance classification is related to the temperature of the hotspot in the insulation occurring during rated operating conditions of the electric motor, allowing for the highest permissible rise in average temperature. This rise should be selected so that at the highest permissible ambient temperature,...

GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Cooling General purpose motors from Cantoni Group are equipped with standard IC411 cooling according to IEC 60034-6. Other cooling methods (for example motors with external/separate cooling) are available on request. IC code according to IEC 60034-6 – Open machine – Fan mounted on shaft – Often called "drip-proof" motor – Enclosed machine – Surface cooled by natural convection and radiation – Without internal or external fan – Enclosed machine – Smooth or finned casing – External shaft-mounted fan – Often called TEFC motor – Enclosed machine – Smooth or...

Standard terminal box equipment Motor frame size Number of cable glands Size of cable glands Permissible cable diameter for cable gland Optional rotation of terminal box Temperature sensors in the winding Thermal protection of bearings Vibration level The rotor balancing method guarantees that a standard vibration level A is maintained in accordance with the IEC 60034-14. On customer’s demand the motors can be produced with reduced vibration (level B). Limits of maximum vibration velocity (r.m.s.) for shaft height H according to IEC 60034-14 H > 132 Fitting type Free suspension Rigid setting...

GENERAL PURPOSE 3-PHASE INDUCTION MOTORS Terminal box The terminal boxes of low voltage motors have threaded inlet holes designed for mounting cable glands. The box contains a terminal board with marked terminals making possible connection of supply cables. In addition, terminal boxes may be provided with additional terminals connected to the ends of thermal protection or anticondensation heater circuits and extra glands to connect these circuits. Starting from frame size 355 motors contain terminal boxes with cable gland seals. The circuits of thermal protection and anticondensation heaters...
