Installation & Maintenance Instruction Manual
MAX MOTION Stainless Steel 3 phase Induction
Motors
This INSTRUCTION MANUAL has been prepared for
personnel authorized to install, operate, and maintain MAX
MOTION Stainless Steel three phase induction motor
SAFELY and PROPERLY.
RECEIVING INSPECTION and HANDLING
- Immediately check the motor for external damage that
may have occurred during shipment and if any is found,
inform the nearest representative of MAX MOTION
without delay.
- Check the nameplate data, especially the voltage and
winding connection.
- Turn by shaft to check it turns freely.
- WARNING! The motor should be lifted by the lifting
eyebolts or the lugs. Those are provided for lifting the
motor only. They must not be used for lifting other
equipment that may be attached to the motor. All eyebolts
must be fully tightened. When lifting the motor be careful
not to damage other parts such as shaft extension, fan
cover, fan, windings etc.
WARNING!!!! The following safety precautions must be
observed.
- Rotating parts of motor and high voltage connections can
cause serious even fatal injury if improperly installed,
operated or maintained. Responsible personnel should be
familiar with NEMA MG2 (Safety Standards for Construction
and Guide Selection, Installation and Use of Electric Motors
and Generators), the National Electrical Code (NEC) and all
local safety regulations.
- When servicing, all power sources to the motor and
accessory devices should be de-energized and disconnected
and all rotating parts should be inactive.
- Lifting devices, when supplied are intended for lifting the
motor only. When two devices are supplied with the motor,
a dual chain must be used.
- Suitable protection must be used when working near
machinery with high noise levels.
- Safety means and protection MUST NOT be by-passed or
rendered inoperative.
- The electric motor frame must be grounded in accordance
with National Electrical Code and the local applicable
regulations.
- A suitable enclosure should be provided to prevent access
to the motor by other than authorized personnel. Extra
caution should be observed around motors that are
automatically controlled or have automatic reset relays; the
motor could restart unexpectedly and cause serious
injuries.
- When belts are used to drive the equipment, belt guard
should be used to prevent injuries that could be caused by
belts breaking.
- Shaft must be free to turn before motor is started.
INSTALLATION / MOUNTING
The motor foundation must be sufficiently rigid as to
minimize vibration and maintain alignment between the
motor and the driven equipment. Motors are dynamically
balanced at the factory to NEMA Standards on Vibration
Limit. However, vibration at the motor and the driven
equipment can occur if the base they are mounted on is not
rigid enough. To minimize vibration, a strong and rigid base
must be provided for the motor and driven equipment.
Only trained personnel should perform installation of the
motor.
Direct Drive application: Direct connected motors may be
coupled to the load through flexible coupling. Coupling half
should not be installed by hammering unless the opposite
end of shaft can be backed up to prevent damages to the
bearings. Accurate mechanical lineup is essential for
successful operation. Align shafts accurately. If reverse
rotation can cause damage to the driven equipment, CHECK
ROTATION before connecting the motor to the load. See
V-belt Drive application:
- Mount motor sheave close to the bearing housing.
- Allow sufficient clearance for rotor endplay.
- The sheave diameter should not be less than NEMA
recommended values. See NEMA MG-1-14.42.
-Align sheaves carefully. Tighten belt only enough to
prevent slippage.
Condensation Drain Holes: On Max Motion Stainless Steel
TEFC motors, condensation drain holes are located at each
end of the stator housing in both drive & non-drive
brackets. Each brackets have 4 provision holes, 90° from
each other. The factory installs the ''T'' condensation plug
for horizontal mounting, feet at the bottom or round body
F1. For any other mounting position, the drain hole plugs
inserted at the factory must be repositioned to in such a
way as to remain the lowest point on the motor to prevent
condensation water build up. Drain plug provisions that are
not used for condensation evacuation while motor is in
operation, must always remain sealed. Sealant must be
used if plugs are removed and reinstalled. Periodic
maintenance schedule should include inspection of drains
to keep them free of debris and free flowing.
Foot mounted motor: Motor should be installed on a rigid
foundation to prevent excessive vibration and should be
fasten securely to a base with maximum size bolts.
Flanged footless motor: All fits are accurately machined to
match with the driven equipment. Matching surfaces
should be free from dirt or burrs and solidly engaged. The
complete assembly should turn freely without stressing
shaft and bearings from misalignment and thrust.
LOCATION
- Stainless steel motors are intended for use in an IP69K
environment. NOTE: in all cases, NO surrounding structure
should obstruct normal flow of ventilating air over motor.
- WARNING! DO NOT INSTALL this motor where hazardous,
inflammable, or combustible vapors or dust are present,
due to the possibility of explosions or fire and damage to
property or injury to personnel.
