Installation & Maintenance Instruction Manual
MAX MOTION CI 3 phase Induction Motors
This INSTRUCTION MANUAL has been prepared for personnel
authorized to install, operate, and maintain MAX MOTION 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 shaft by hand to check if 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 Start Up.
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 Cast Iron TEFC
motors, condensation drain holes are located at each end of the
stator housing where the feet are located and on the face of the
output flanged motors (TC, JM, JP). The drain hole plugs installed
at the factory, must be removed to prevent condensation water
build up. On horizontal F1 or F2 installations, remove plugs
located at each end of stator. In vertical output shaft down flange
mounded installations, remove plugs located on Face of output
flange. 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
- ODP (Drip-proof)) motors are intended for use where
atmosphere is relatively clean, dry, and non-corrosive. Keep
windings clean with soft brush, cloth, or vacuum.
- Totally-enclosed motors may be installed where dirt, moisture
and corrosion are present.
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.
ELECTRICAL CONNECTIONS
- this motor was design in accordance with NEMA MG1 standards.
As such, it is designed to operate at ± 10% nominal voltage at
rated frequency. A 1% voltage unbalance will cause a significantly
much larger current unbalance and possibly cause the motor to
overheat.
- Connect motor to correct power supply according to nameplate.
- Motor and control wiring, overload protection and grounding
should be done in accordance with the National Electric Code and
local regulations.
- Identify motor auxiliary device such as space heater or
temperature sensors. These should have their own isolated
circuits insulated separate from the motor power cables.
