SINGLE-PHASE INDUCTION ELECTRIC MOTORS

Series ES - single-phase motors with starting capacitor sizes 80 and 90.

Series ER - single-phase motors with running capacitor sizes 56, 63, 71, 80 and 90.

Series ESR - single-phase motors with starting and running capacitors sizes 80, 90 and 100. Series ERR - single-phase motors with running capacitor and high starting torque sizes 80 and 90. The single-phase induction electric motors with squirrel cage rotor series ES, ER, ERR and ESR have external self-ventilation by own fan and are designed for universal application.
DESIGN

The longitudinally ribbed frames of the motors are made of: aluminium alloy for electric motors sizes 56, 63, 71 and 80 aluminium alloy or cast iron for electric motors size 80, 90 and 100.

The bearing shields are made of: aluminium alloy for electric motors sizes 56, 63 and 77; aluminium alloy or cast iron for electric motors sizes 80, 90 and 100.

The rotor axial clearance is compensated by a spacing ring fixed in the rear bearing seat.

The fan cover is made of sheet steel.

The fan is made of plastics.

The stator winding is made of enamelled copper wire. The terminal box of the foot-mounted motors (execution IM B3) is located on top.

SUPPLY VOLTAGE AND FREQUENCY

The supply voltage of the electric motors is 230V at frequency of 50Hz.

The electric motors can also be designed for other rated voltages at frequency of 50 or 60Hz on request.

Supply voltages deviation should not exceed its rated value by more than ± 5%. Frequency deviation should not exceed its rated value by more than ± 2% (zone A) as per EN 60034-1.


PROTECTION

The degree of protection of the motors is IP 54 or IP 55 as per EN 60034-5.
INSULATION CLASS

Insulation class - Fas per EN 60034-1.
O PERATING CONDITIONS

The electric motors are designed for continuous operation at duty cycles (S1) in the conditions of Moderate climatic area as per DIN IEC 721-2-1, at temper­atures from -10 °C up to +40 °C for series ES and ESR, from -25 °C up to +40 °C for series ER and ERR. Altitude up to 1000 m, and humidity up to 85%.

The electric motor output is reduced when operating under conditions different than the specified above.

The electric motors can operate at duties (different from S1) on request.

The electric motors can be executed for operation in a Worldwide tropical climatic area.
