Kinetix MMA Asynchronous Main Motors Installation Instructions
Before You Install the Motor
Review all sections. Perform these steps and inspections before you begin installation.
1.
Remove the motor carefully from its shipping container.
2.
Inspect the motor for any damage.
3.
Examine the motor frame, motor shaft, and mounting surfaces for any anomalies.
4.
Notify the carrier of shipping damage immediately.
5.
Verify that all components and accessories are present and undamaged.
Prolong Motor Life
Proper installation and motor maintenance can help prolong motor life. Follow these guidelines and the
Environmental Ratings on page 58
to maximize the life of a motor.
• Create a drip loop in the motor cables to carry liquids away from the motor connection.
• Whenever possible, provide shields that help protect the motor housing, shaft, seals, and their junctions from contamination.
• Shaft seals are subject to wear and require periodic inspection and replacement. Replacement is recommended every 3 months, not to exceed 12 months,
depending on the use. See
for more information.
• Follow all of the topics listed in the
section of this manual.
• Inspect the motor for damage or wear regularly. If you detect damage or excessive wear, contact
.
In cases where the startup is not immediate, some precautions must be taken to help protect the motors during storage.
• Keep the motor in a clean and dry covered place, which is protected from possible impacts and position it horizontally. See
• Be sure to help protect the motor from debris that could get inside the motor or the blower.
• Do not store the motor in open spaces or wet environments.
• It is recommended to rotate the motor shaft manually every 2…3 months.
Help Prevent Electrical Noise
Electromagnetic interference (EMI), commonly called electrical noise, can reduce motor performance. Effective techniques to counter EMI include filtering the AC power, by
using shielded cables, shielding the signal cables from power wiring, and the practice of good grounding techniques.
Follow these guidelines to avoid the effects of EMI:
•
Isolate the power transformers or install line filters on all AC input power lines.
•
Do not route motor cables over the vent openings on drives.
•
Ground all equipment by using a single-point parallel ground system that employs ground busbars or large grounding straps.
If necessary, use additional electrical noise reduction techniques to reduce EMI in noisy environments.
See System Design for Control of Electrical Noise Reference Manual, publication
, for additional information on reducing EMI.
Minimum Mounting Clearances
Install the motor in a well-aired, clean, and dry environment. Where the motor is installed inside a cabinet or similar enclosure, it is necessary to provide openings for
ventilation, inspection, and maintenance. Verify that walls, sides of the machine, bins, or containers, do not impede the air circulation. Avoid having warm airflow around the
motor. In cases where the installation environment is in open air, with floating particles, or other unfavorable air quality conditions, verify the risk of using the motor and
determine the precautions that are necessary.
The motor dissipates heat through an auxiliary electric blower. This blower generates a constant airflow, regardless of the rotation speed of the motor. The airflow is
directed through the ventilation ducts or onto the cooling fins over the entire surface of the motor’s external structure (frame and covers).
See
for minimum mounting clearance information.
ATTENTION:
You are not permitted to disassemble the mechanical components of the motor; the
exceptions are: the blower, shaft seal, and the standard encoder replacement procedures. All other motor
maintenance must be performed by a Rockwell Automation authorized service center.
IMPORTANT
For the IC17 clean-air option, additional ventilation requirements exist. Follow applicable standards.
