Multi-plate clutches type ETM-..2 are designed exclusively for operation in oil. Transmissible torque 20÷1600 Nm.

They are designed to be powered with 24 ± 1 V DC through a brush holder type EMS-2A… or SV – 22 . . The negative pole of the power source should be connected to the machine body and the positive pole to the brush holder . At coupling contact ring speeds exceeding 10 m / s , it is recommended to use _ _two brush holders shifted relative to each other by max. 90 ∞ . In order to protect the clutch coil against breakdown in the supply system , a suppression element should be used in the form of a resistor connected in parallel to the coil with a resistance of about 10 times higher from the resistance of the coil, or semi – conductor diode , orresistor and diode.
