Electric Motor; Electric Motor Reference Standard (Eu); Connection - FPZ MOR Series Instructions Manual

Use pushers or pullers for fitting and removal of the semi-joints from the shafts - DO NOT USE A
HAMMER. The percussion can ruin the bearing races and shorten their life.
NOTE FOR THE USER
The coupling requires precise axial and angular alignment which, if not satisfactory, compromises the life
of the transmission and bearings.
Regarding this, also consult the instruction manual for elastomer couplings.

Check the axial alignment of the semi-joints in at
least four places using a knife-edge rule or similar.

Check the angular alignment by measuring the
distance of the semi-joints in at least four places.

Do not turn the transmission in taking the
measurements.

Make sure the correction of one alignment does
not change the other.

Protect the couplings with the coupling covers,
fixing them to the connection flange using suitable
screws.
NOTE FOR THE USER Regarding this, also consult the instruction manual for elastomer couplings.

12.4 ELECTRIC MOTOR

The side channel blowers are equipped with electric motors with specifications: single-phase, two-pole three-phase, continuous duty
(S1), according to efficiency class as per the current regulations.
The motors of K series MOR version and R series MOR/GOR version side channel blowers have PTO thermal protectors (standard),
PTC on request.
Danger of sudden restarting.
The PTO thermal protector is an normally-closed electromechanical device. Once the tripping temperature is reached, it opens and
stops the electric motor. The electric motor resumes normal operation when the temperature falls below the trip threshold. Take
suitable steps to prevent injury and damage to property in case of sudden restarting.
ATTENTION!
The units are equipped with motors S1 for continuous operation.
A maximum of 6 starts per hour, equally distributed, are permitted. Non-compliance can damage the unit.
For GOR version blowers, comply strictly with the safety measures and instructions given in the
electric motor instruction manual.
12.4.1

ELECTRIC MOTOR REFERENCE STANDARD (EU)


The electric motors that power the machines are CE marked

The wide range three-phase electric motors supplied by FPZ that power MOR version blowers ensure correct operation in the
range of voltages specified on the rating plate, which is wider than that provided for by the regulations for standard motors:

Up to 4.0 kW inclusive: 345-415/200-240V 50Hz - 380-480/220-280V 60Hz. IE2 only 230/400V-50Hz

5.5 kW to 15 kW inclusive: 600-720/345-415V 50Hz - 660-830/380-480V 60Hz. IE2 only 400/690V-50Hz

MOR version blowers with electric motors exceeding 15 kW are not wide range, and are not IE2

The electric motors comply with EU regulation 4/2014 and the efficiency class specified in standard IEC 60034-30
