Six Steps for a Perfect Electric Motor Installation
So, you’ve ordered an electric motor for your application. Before you begin the installation process, check out the following steps for perfect installation.
Handling & Storage
First, inspect your new motor for scratches, defects, or dents. Also, be sure to confirm that the nameplate information matches your order. Don’t accept delivery of your motor unless you’re satisfied with the conditions and specifications.
Make sure your motor will be kept in clean, dry conditions and away from sources of shock or vibrations. In the storage area, aim to maintain an ambient humidity of 60% or below, and an average temperature between 10 and 50 degrees Celsius.
For storage, select a location that’s well ventilated and not surrounded by walls or any other objects that may affect the ambient temperature. The temperature on the motor nameplate should not be exceeded. If the operating environment exposes the motor to dust and moisture, be sure it will carry the appropriate IP rating.
One of the essential components for mounting an electric motor is a level base. Each of the motor’s mounting points must sit on the same plane. A reinforced concrete foundation allows the motor to attach and reduces vibration. Slight adjustments can be made by placing shims beneath the motor feet.
Tighten the foot bolts in sequence to avoid soft foot. Also, the feet and mounting base should be completely free of debris.
If you properly align your electric motor to the driven machine, you’ll reduce energy loss triggered by friction and vibration. The systems process efficiency will improve, and productivity will increase. Successful mounting and laser alignment helps the shafts line up with the maximum precision.
In most cases, oil lubricated motors are distributed dry from the factory. Read over the manufacturer’s guidelines to find the best type and quantity of lubricant to use. Effective lubricant reduces friction between the shaft and bearings. The lubricant also directs heat away from hot spots, safely cooling the motor. Improperly lubricating the system can produce friction, and ultimately cause it to overheat. However, using too much lubrication can cause energy loss and force the lubricant out of the system.
Ensure the power source voltage, frequency, and phase match the motor’s nameplate data. Confirming these details can help you make sure the current capacity can maintain the rated voltage under any load condition.
