x) Capacitors (For Single Phase Motors):
Each single phase motorized pulley requires an appropriate capacitor. For models 80LS to 320L RUN capacitors are
supplied with the pulley. Detailed information available on request. Using other than the specified RUN capacitors
may damage the motor and voids product warranty.
The RUN capacitors must be permanently connected to the motor, as shown on the connection diagrams.
RULMECA single-phase motors are "permanent split phase motors". Each motor is supplied with two windings. They
are designed so that an appropriately sized capacitor connected to one of the windings will start the motor rotating.
Starting torque is limited to 70% of full running torque.
It is possible to increase starting torque to 100% by adding a second appropriately sized capacitor (START capacitor)
to the circuit. Note that this circuit must be designed to drop the starting capacitor out of the circuit after the motor
has reached its nominal speed. Contact RULMECA for more information on how to run single-phase motors using
START and RUN capacitors.
y) Maintenance:
Normally Motorized Pulleys are maintenance free and require no specific attention during their operation.
They are ready for operation immediately after connection to the power supply.
If repair or maintenance is required, the Motorized Pulley has to be disconnected from the
supply before the terminal box can be opened. Turn the electrical power off at the electrical panel
board (circuit breaker or fuse box) and lock or tag the panel board door to prevent someone
from turning on power while you are working on The unit, failure to do so could result in serious
electrical shock, burn or possible death.
During a test run, the shaft ends must be correctly fixed to the support frame, and suitable guarding
must be provided around the rotating parts, for the protection of all personnel.
WARNING: DO NOT operate without guards in place. Failure to follow these instructions could result in
death or serious injury.
z) Aftermarket Service
Always contact your local authorized RULMECA service centre or distributor for aftermarket service or please refer to
nearest RULMECA distributor listed on the back of our catalogue. Alternatively please refer to www.rulmeca.com.
aa) Wiring Diagrams
Will be listed on the last 3-5 of the catalogue – prior to OPTIONAL EXTRAS and placed into the terminal box.
bb) Non-Belt, Partial Belt, Modular Belt
Special motorized pulley designs are available for "non-belt, V-belt, partial belt, and modular belt" applications. See
"ambient temperature section" above.
It is essential that each special application is designed to adequately dissipate heat from the pulley surface.
Using a standard motorized pulley in one of these special applications could result in motor heat damage and voids
product warranty.
Contact RULMECA for assistance with these applications.
cc) Storage of Motorized Pulleys
During storage RULMECA Motorized pulleys
should be stored in a house or as a minimum covered by an awning.
have to be protected against direct influence of the sun to secure that the sealing system does not dry out!
have to be turned 180° every ½ year to make sure that all internal parts are being lubricated.
If Motorized Pulleys have stored longer than 1year, they have to be tested before being put into operation. Such a test
should include that
The motor winding is checked with an insulation tester
The winding resistance is checked
The thermal protector is checked with continuity tester
The pulley is connected to the power supply and runs for a minimum of 30 minutes to check that there is NO oil leaks
– make sure that the pulley body temperature DOES NOT exceed 70°C degree.
For safety reasons make sure that the pulley is proper fixed to the test frame during test.
