Too low or too high mains voltage or frequencyĥ. Overload (electric motor is overloaded)Ĥ.
Starting too heavy (electric motor is overloaded)ģ. Electronic thermal protection (thermistor in the winding of the electric motor) – mark EĮlectronic thermal protection represents complete protection of the electric motor because it reacts in the following cases:Ģ. Automatic thermal protection (bimetal in the winding of the electric motor) – mark AĢ. At the request of customers, we install the following in electric motors:ġ. Single-phase electric motors can also be protected by users themselves with circuit breakers (see page 10). drive capacitorī.) single-phase electric motors with starting capacitorĬ.) single-phase electric motors with starting and drive capacitors. Upon special request, we can also produce electric motors for other voltages and frequencies.ĭepending on the implementation of the auxiliary phase, we divide single-phase electric motors into:Ī.) single-phase electric motors with a permanently connected, i.e. Standard electric motors are electric motors built for connection to the 230V, 50Hz network. if the electric motors must comply with regulations other than IEC 60034 or DIN VDE 0530 T1. if electric motors are operated at a special driveĤ. if the mains voltage or frequency changes by more than ± 6%ģ. The power of the electric motor may decrease or increase if the following operating conditions are changed:ġ. The powers given in the tables are the rated powers emitted by the electric motors on the shafts at constant load, at rated voltage and frequency, at an ambient temperature not exceeding 40☌ and at an altitude of up to 1,000m. Single-phase electric motors have the same bearings as three-phase electric motors of the same size, except for electric motors with a starting capacitor (EKSK 100 and EKSK 112), where 6205 2Z bearings are installed on the N side. One or more capacitors are mounted on single-phase electric motors. Electric motors (3) ESK and (3) EKSK have a built-in centrifugal switch in the bearing shield on the N side. Automatic thermal protection switches and thermal sensors are built into the windings of electric motors.
The capacitors are attached to the top of the stator housing with special clamps and connected to the terminal block in the cabinet. The normal design is IM B3 and the protection level is IP 54.
Single-phase electric motors are similar in design to three-phase IEC electric motors. The electric motors comply with DIN VDE 0530 T1. The installation dimensions are in accordance with the recommendations of IEC publication 60072. Data from single-phase electric motors with a short-circuit cage for the power range from 0.045 kW to 2.2 kW are described.
