Note
Characteristic curves apply
to motors without gear unit.
The gear unit data must be
taken into consideration for
motors with gear unit.
Example
Nominal torque for motor
MTR-AC-55-3S-... at a
nominal speed of 3000 rpm
Without Gear Unit:
Nominal torque = 0.88 Nm
(see characteristic curve)
With Gear Unit:
Gear reduction ratio = 4:1
Gear unit efficiency = 0.95
Nominal rpm = 3000/4 = 750
Nominal torque = 0.88 Nm x 4 x 0.95 = 3.34 Nm
