EX, SGX VIBRATOR MOTORS
DESCRIPTION
Motion is generated by the vibrator motors and transmitted to the screen frame to separate and
conveys solids over the screen panels. The EX and SGX motors are rated for continuous duty
with Totally Enclosed Non-Ventilated (TENV) construction and permanently lubricated, sealed
bearings. Depending on the screening equipment, one or two motors are installed.
Eccentric weights installed on the rotor shaft produce the motor’s vibratory action. The weight,
which is measured in in-lbs, varies depending on the application and equipment on which the
vibrator motor is installed. The weight is stamped on the motor nameplate. When two vibrator
motors are installed on a single screen frame, the motors are connected to cause the motors to
rotate in opposite directions for maximum G-forces.
The vibrator motors must be operated at their rated three-phase supply voltage. Motors are
available in both explosion-proof and non-explosion-proof versions. The model designation shown
on the nameplate is defined as follows:
EX 30 – 18 – 460/480 – 6 000

STORAGE
If a spare motor is to be placed in storage, the instructions in the following paragraphs must be
observed to protect the stored motor and maintain the warranty.
New Motors
New spare vibrator motors should be stored in a clean, dry (50 percent relative humidity or less),
warm location. The storage location should not undergo severe daily temperature changes.
Used Motors
Before storing a motor that has been in service, run the unit for approximately one hour to ensure
complete heating and to dissipate any internal moisture. At the end of the run, shut down the
motor and allow it to cool. Follow all applicable lock out and tag out rules when removing the
motor.
While motor is in storage, periodically check the integrity of the winding insulation using a
megohmmeter. Maintain a continuous record of megohmmeter readings, and immediately
investigate any significant decrease in insulation resistance.
OPERATING ENVIRONMENT
Derrick vibrator motors are designed to operate in ambient temperatures slightly higher than
104°F (40°C). If higher temperatures are anticipated, please contact the Derrick Technical Service
Department for assistance. DO NOT install hoods or enclosures that may cause inadequate
ventilation, which could reduce vibrator life.

Connections to Motor
The procedure below describes motor cord connections to the motor. If replacing a cable, tag all
leads for identification before disconnecting old cable. The EX and SGX motors use either the
following connection styles:
Terminal Block - Cord is fed through the side of the motor junction box and connected to a
terminal block inside the junction box
Power Connector - Cord is fed through the junction box cover, which contains a female power
connector where connections are made. This connector plugs into a male plug in the junction box.
Terminal Block Style
1. Remove cover from motor junction box.
2. Carefully feed the wires through the elbow installed in the motor junction box (Figure 2).
3. Install and tighten gland assembly components in elbow, using care to avoid over-tightening
backnut. To prevent over-tightening, stop tightening backnut when red seal begins to swell.
4. Install two O-rings over leads inside junction box, slide both O-rings into threaded hole in box,
and position one O-ring at each end of threaded hole to suspend the leads in the center of the
hole.
Note! Be sure that O-rings are properly installed, as they prevent chafing of
leads due to abrasion against threaded hole.
5. Route leads as shown, dressing carefully to prevent leads from contacting each other or the
interior of the connection box.
6. Secure black, white, red, orange, and blue leads to studs as marked on terminal block using
external tooth lockwashers and Flex-Loc®nuts. Secure green lead to GROUND terminal using
lockwasher and screw.
7. Apply RTV-108-10.1 silicone sealant to leads (Figure 3) for vibration-proofing. Also, be sure to
fill threaded hole for additional protection against chafing.
8. Place cover on motor junction box, and install and tighten four screws to 250 in-lbs.

6. Apply small amount of LubriPlate 5555, part number L0107-007, or UL-approved equivalent to
new O-ring, and install O-ring in groove of cover.
7. Align cover mounting holes with holes in junction box, ensure that O-ring remains in place,
and install cover by engaging power connector plug and receptacle.
Note! Be sure that connector halves mate easily and that O-ring remains in
place during assembly.
8. Secure cover to junction box with four socket head cap screws, and tighten to 250 in. lbs.
9. Check for proper fit between cover and junction box surface by attempting to insert a 0.001”
shim between the two parts around the entire mating area circumference. If the shim can be
inserted at any location, remove the cover and correct any defect.

Connecting Motor Cord To Junction Box
Motor leads may be connected inside a round or rectangular junction box. If a round junction box
is installed, the motor leads are connected to the machine leads with wire nuts and tape (Figure
5). If a rectangular junction box is present, the leads are connected to the terminal block shown in
Figure 6 for dual motors or Figure 7 for a single motor. Refer to the schematic diagram in your
equipment manual for additional assistance in connecting single or dual vibrator motor(s). The
following procedures cover all types of installations. Select the procedure that applies to the
electrical configuration of your machine.
Motor Power Connections to Round Junction Box
1. For machines having an elbow installed in a round junction box, wrap leads loosely with
electrical tape to facilitate threading through elbow in conduit.
2. Pass leads through junction box elbow and into junction box (Figure 5). Thread front gland nut
into junction box elbow, and tighten securely. Thread rear gland nut onto front gland nut, and
tighten securely. Thread and tighten backnut onto cable gland. Using wire nuts and electrical
tape, connect leads to corresponding wire colors inside junction box as shown.
Note! In dual-motor machines, be sure to connect one motor in reverse
polarity so that motors rotate in opposite directions.
Motor Power Connections to Rectangular Junction Box
1. Pass leads into junction box (Figures 6 and 7), and thread front gland nut into junction box
and tighten securely.
2. Thread and tighten rear gland nut onto front gland nut.
3. Thread and tighten backnut onto rear gland nut.
4. Insert wire colors into proper locations on terminal block as shown, noting that for dual-motor
machines leads for one motor are reversed. Tighten terminal screws to secure leads.
Note! In dual-motor machines, be sure to connect one motor in reverse
polarity so that motors rotate in opposite directions.
