Werner Motor Company
The permanent split-capacitor AC motor is designed with a
low operating temperature without sacrificing
starting and running torque.
Single-phase motors are available at either 115 volts
(60 Hz), or 220 volts (50Hz and 60 Hz). Other voltages
and frequencies in single-phase motors are also available.
Electrical stators are insulated as NEMA class B and require
an externally mounted capacitor.
All motorized pulleys are equipped with a resettable
internal thermal overload fuse that will disconnect
power if motor windings reach excessively high temperatures.
This protection is the best safeguard available against motor
failure. Motors are reversible and have a duty-cycle
of 30 starts/stops per minute.
Our motors are capable of driving belts for small part conveyors
The planetary gear system, which has
either two or three stages of reduction, is molded of high
precision injection-molded acetal plastic to ensure the lowest
possible noise level. This gear system is designed
to withstand overload. Various gear combinations generate
fixed belt speeds.
The motor cylinder tube
has a trapezoidal crown machined for optimum belt traction
and tracking, in accordance with specifications of most conveyor
belt manufacturers. A coating of Rust-Ban is
applied to the tube to protect it against corrosion during
transportation and storage.
The motorized pulleys contain Esso NUTO H68 oil or an equivalent,
which lubricates all internal moving parts to cool the electrical
motor. For this reason, the the unit should be mounted horizontally.
Since the belt helps to remove heat from the drive pulley, it should
not normally be operated without a belt. These pulleys never
require an oil change.
patented oil agitator circulates the oil to distribute heat evenly
over the width of the pulley. This allows for easier belt tracking
and lower belt temperatures.
seals, running on a precision centreless ground shaft, prevent
entry of dust, dirt and moisture, while preventing
loss or contamination of oil. In addition, rubber-sealed
ball bearings and end caps provide further protection. As a result,
the unit is maintenance-free.
