As we approach the fall months, it’s time to do a quick run-through with your furnace to make sure it’s ready to handle your home’s heating needs. While there are many simple tasks that you can do to make sure your furnace is running properly, it is recommended that a HVAC professional tune-up your furnace […]
After a motor is rewound, the windings must be further insulated with resin or varnish. This insulation protects the windings from contamination, shorting electrically, and also make the windings more mechanically rigid. What are the different types of varnishing methods? There are four types of varnishing methods that we will describe below: Dip and Bake […]
The lifetime and efficiency of motors can greatly be affected by their environment. In our blog, Electric Motors and Generators Fail from Contamination, we discuss the affects of contamination and how you can prevent downtime. In addition to taking preventative measures discussed in our contamination blog, you may want to consider protecting your windings with […]
V-belts are an important part of a power transmission system. They allow for the transfer of energy from one source to another. While belts require little maintenance, they can greatly be impacted by improper belt tension. As discussed in our Common Belt Problems blog, improper belt tension is a leading cause of issues in your […]
Why Shaft Alignment Matters Alignment in your machines is vital to the reliability of your operations. When two machines are misaligned, severe failure can occur causing unplanned downtime and loss of revenue. Some negative consequences are seal failure, bearing failure, energy loss from inefficiencies, increased vibration, and excessive heat. Common Shaft Alignment Issues For normal […]
Variable Frequency Drives (VFDs) are used to adjust the speed of motors. There are many different names for VFDs including adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter drive. VFDs adjust the speed of motors by changing the frequency being transferred to the motor. For example, when the VFD is receiving power […]

Aegis Shaft Grounding Rings protects bearings and electric motors from damaging shaft voltages caused by variable frequency drives (VFDs). The voltages emitted by VFDs find their way to ground typically through the motor’s bearing. Some signs of these damaging currents include pitting, frosting, fluting and loss of bearing lubrication. Installing Aegis Shaft Grounding Rings to […]
“My original condenser fan motor has three wires and the replacement condenser fan motor that I bought has four wires – did I buy the wrong motor?” This is by far the most common post-transaction question that we receive from customers that have recently purchased replacement condenser fan motors. Simply put, no – you did […]
