Induction motors of series 4TM, 5TM

Basic Information

Motors of 4TM series are induction motors with squirrel cage rotor, 4TM are three-phase and 4JMC are single-phase with capacitor.


Motor frame, both shields and terminal box are made of alluminum alloy, fan is made of plastic, fan cover is manufactured from steel sheet.


Motors have windings from copper conductors, insulation category F, stator and rotor are made from steel sheets for electrotechnic. Rotor cage is cast from aluminium. Rotor body is pressed on the shaft, dynamically balanced with a half-key and deposited in ball bearings of 62 and 63 series. All bearings are in 2Z series.

Free shaft end is provided with female screw acc. to DIN 332.

Heavy series of induction motors 5TM – three-phase induction motor with frame and shields from grey cast iron, suitable for heavy industrial traffic with high mechanical stress, vibrations and severe environment.
