AC & DC Motor Installation Instructions
These instructions are intended to complement (not
replace) the information in MN400 Installation and
Operation manual for “Integral Horsepower AC
Induction Motors ODP, TEFC, Explosion Proof’ and
MN605 Installation and Operation manual for
“Integral Horsepower DC Motors”.
Handling:
The weight of the motor and shipping container will
vary. Use correct material handling equipment to
avoid injury.
Use caution when removing the motor from its
packaging. Sharp corners may exist on motor shaft,
motor key, sheet metal and other surfaces.
Receiving:
The Motor shaft should rotate freely with no rubs.
Report any damage immediately to the commercial
carrier that delivered your mixer.
Safety Notice:
Only qualified personnel trained in the safe
installation and operation of this equipment should
install this motor. When improperly installed or used,
rotating equipment can cause serious or fatal injury.
Equipment must be installed in accordance with the
National Electrical Code (NEC), local codes and
NEMA MG2 Safety Standards for Construction and
Guide for Selection, Installation and Use of Electric
Motors and Generators. Observe the following
guidelines:
1. When eyebolts are provided, they must be fully
tightened and are intended to lift the motor and its
included accessories only.
2. Ground the motor according to NEC and local
codes.
3. Provide a permanent guard to prevent accidental
contact of body parts or clothing with rotating or
moving parts or burns if motor is hot.
4. Shaft key must be secured before starting motor.
5. Do not apply power to the motor until the motor is
securely mounted by its mounting holes.
6. This motor must only be connected to the proper
line voltage, line frequency and load size.
7. Motors are not to be used for load holding or
restraining unless a properly sized brake is installed.
If a motor mounted brake is installed, provide proper
safeguards for personnel in case of brake failure.
8. Disconnect all power services, stop the motor and
allow it to cool before servicing.
9. For single phase motors, discharge the start
and/or run capacitors before servicing.
10. Do not by-pass or render inoperative any safety
device.
11. DC series wound motors must be protected from
sudden loss of load causing overspeed damage. DC
shunt wound motors must be protected from loss of field
voltage which can result in damage.
12. When using AC motors with frequency inverters, be
certain that the motors Maximum Speed Rating is not
exceeded.
13. Mounting bolts should be high tensile steel. Be sure
to use a suitable locking device on each bolt (spring
washer or thread lock compound).
Motor Enclosure Information:
ODP, Open drip proof motors are intended for use in
clean, dry locations with adequate supply of cooling air.
These motors should not be used in the presence of
flammable or combustible materials. Open motors can
emit flame and/or molten metal in the event of insulation
failure.
TEFC, Totally enclosed motors are intended for use
where moisture, dirt and/or corrosive materials are
present in indoor and outdoor locations.
Explosion proof motors, as indicated by the
Underwriters Laboratories, Inc. label are intended for
use in hazardous areas as specified by the NEC.
Mounting:
Foot mounted machines should be mounted to a rigid
foundation to prevent excessive vibration. Shims may be
used if location is uneven.
Flange mounted machines should be properly seated
and aligned. Note: It improper rotation direction is
detrimental to the load, check rotation direction prior to
coupling the load to the motor shaft.
Direct coupled machines should be carefully aligned
and the shaft should rotate freely without binding.
