As a standard, Auma multi turn actuators are
equipped with 3 phase induction motors.
Auma motors are class F insulated and
The motors are used for short time duty (S2-15
min or S4-25% as per IS 12824) and provide
approximately three times rated torque for
short duration. The size of the motor is smaller
compared to continuous duty motor S1 of
same output power. This results in reduced
inertia of the rotor and therefore less
overshoot after switching off of motor. Auma
motors are designed for enclosure protection
class IP 68 when mounted on the actuator. All
motor cables are brought to terminal
compartment cover from inside of the actuator
o
withstand winding temperature upto 140 C.
thus avoiding terminal box.
Three phase induction motors are available in
wide range of operating voltages from 220 V to
560 V and operating frequency of 50 or 60 Hz.
Auma actuators are also available with DC
motors. These motors operate on 24 V, 110 V or
