Installation Manual MN451 available for download at http://www.baldor.com/support/product_manuals.asp. Be sure to read and understand all of the Safety Notice statements
in MN451 EC Titanium Manual for your motor. The basic design includes Class F insulation, Class B temperature rise, 1.5 service factor motor only (1.0 SF integrated motor drive
designs), 40°C ambient, continuous duty. Standard enclosures are totally enclosed fan cooled foot mounting. It is important that motors be installed in locations that are compatible
with motor enclosure and ambient conditions. Improper selection of the motor enclosure and ambient conditions can lead to reduced operating life of the motor. Proper ventilation
for the motor must be provided. Obstructed airflow can lead to reduction of motor life.
RECEIVING AND INSPECTION
The EC Titanium is thoroughly tested at the factory and carefully packaged for
shipment. When you receive your motor or the integrated motor and drive, there are
several things you should do immediately.
1. Carefully Unpack the EC Titanium and check for any signs of damage. Notify the
shipper immediately if any exist.
2. Check the motor and / or motor and drive rating label to ensure it is of the correct
type and power requirements for the application.
3. If the motor is to be stored for several weeks before use, be sure that it is stored in
a clean and dry environment and within a temperature range of –40°C to +60°C.
4. After storage or after unpacking and inspection to see that all parts are in good
condition, rotate the motor shaft by hand to be sure there are no obstructions
to free rotation. Motor leads must be isolated before the shaft will turn freely on
permanent magnet motors.
On motors received from the factory with the shaft blocked, remove blocking before
operating the motor. If motor is to be reshipped alone or installed to another piece of
equipment, the shaft block must be installed to prevent axial movement and prevent
brinelling of the bearings during shipment.

MOTOR ENCLOSURE
TEFC, totally enclosed motors are intended for use where moisture, dirt and/or corrosive
materials are present. The EC Titanium motor only is rated for in indoor and outdoor
locations. Integrated drive motor units with plastic covers are indoor use and not rated
for direct sunlight or outdoor use.
GENERAL
The user must select a ac drive suitable for permanent magnet motor control. The
ABB ACH580 is suggested and designed to automatically ID run the EC Titanium
motor. For all other ac drive controls, ensure the drive is capable of permanent magnet
motor control. Values identified on the motor nameplate must be available to enter into
drive parameters. These are shown in the previous section of this guide and include
Motor Rated Amps, Motor Back EMF Voltage, Rs (motor stator resistance), Ld (d-axis
inductance), Lq (q-axis inductance) and motor rated frequency. Ensure the drive is sized
properly for the current rating of the motor and set appropriate overcurrent protection
suitable for this motor and its application.
Speed Range
EC Titanium Motors are rated for a 10:1 Constant Torque Speed range below base
speed. 140 and 180 Frame motors may be operated to a maximum safe speed of 4000
RPM and 210 Frame motors 3000 RPM.
TESTING
If the motor has been in storage for an extensive period or has been subjected to
adverse moisture conditions, check the motor insulation resistance with a meg ohm
meter. Depending on storage conditions it may be necessary to rotate or change rusted
bearings. Contact your local sales office if resistance is less than 5 meg ohms.
WARNING: Do not touch electrical connections before you first ensure that power
has been disconnected. Electrical shock can cause serious or fatal injury.
WARNING: Be sure the system is properly grounded before applying power.
Electrical shock can cause serious or fatal injury.
ELECTRICAL INSTALLATION
This motor must be installed in accordance with National Electric Code, NEMA MG-2,
IEC standards or local codes.
WARNING: EC Titanium permanent magnet motors can induce voltage and
current in the motor leads by rotating the motor shaft. Electrical shock can cause
serious or fatal injury. Therefore, do not couple the load to the motor shaft until
all motor connections have been made. During any maintenance inspections, be
sure the motor shaft will not rotate.
WIRING
Connect the motor as shown in the connection diagrams. If this motor is installed as
part of a motor control drive system, connect and protect the motor according to the
control manufacturers diagrams. Refer to MN408 for additional details on lead marking.
The wiring, fusing and grounding must comply with the National Electrical Code or
IEC and local codes. When the motor is connected to the load for proper direction of
rotation and started, it should start quickly and run smoothly. If not, stop the motor
immediately and determine the cause. Possible causes are: low voltage at the motor,
motor connections are not correct or the load is too heavy. Check the motor current
after a few minutes of operation and compare the measured current with the nameplate
rating.
GROUNDING
Ground the motor according to NEC and local codes. In the USA consult the National
Electrical Code, Article 430 for information on grounding of motors and generators, and
Article 250 for general information on grounding. In making the ground connection, the
installer should make certain that there is a solid and permanent metallic connection
between the ground point, the motor or generator terminal housing, and the motor or
generator frame. In non-USA locations consult the appropriate national or local code
applicable.
Noise
For specific sound power or pressure level information, contact your local sales office.
VIBRATION
This motor is balanced to NEMA MG1, Part 7 standard.
WARNING: Guards must be installed for rotating parts such as couplings, pulleys,
external fans, and unused shaft extensions, should be permanently guarded to
prevent accidental contact by personnel. Accidental contact with body parts or
clothing can cause serious or fatal injury.
DRAIN PLUGS
One or more condensation drain fittings are provided on each endplate for various
motor mounting configurations. The fittings allow drainage and prevent insertion of
a 1mm wire probe per the IP54 rating requirements. To avoid condensation inside
the motor, do not unpack until the motor has reached room temperature. (Room
temperature is the temperature of the room in which it will be installed). The packing
provides insulation from temperature changes during transportation.
MOUNTING
Mount the motor on a foundation sufficiently rigid to prevent excessive vibration.
Standard stock EC Titanium motors are provided with feet for mounting at any angle.
Mounting provisions may also be provided on custom design motors to allow for direct
coupled (c-face) or flange mounting at any angle. After careful alignment, bolt motor
securely in place. For foot mounted motors, use shim to fill any unevenness in the
foundation. Motor feet should sit solidly on the foundation before mounting bolts are
tightened.
EC Titanium Stock Motors are designed to be mounted by the “Mounting Feet”. Use
appropriate hardware (not furnished). The motor should be installed in a location
compatible with the motor enclosure and specific ambient. The motor must be securely
installed to a rigid foundation or mounting surface to minimize vibration and maintain
alignment between the motor and shaft load. Failure to provide a proper mounting
surface may cause vibration, misalignment and bearing damage. All hold down bolts
must be the correct grade for the type of mounting and must be torqued to their
recommended value. The standard motor base is designed for horizontal or vertical
mounting.
