Electric motors are the workhorses of countless industries and households, powering everything from industrial machinery to household appliances. To ensure reliability, safety, and interoperability, standards have been established by organizations like the National Electrical Manufacturers Association (NEMA) and the International Electrotechnical Commission (IEC). Let’s delve into these standards and understand their significance in the realm of electric motors. NEMA Standards What is N...

Proper storage for electric motors is essential for the equipment. In the long term, properly storing the motor can help maintain its performance and reduce repair costs. Dreisilker, with over 68 years of experience in electric motor repair, provides a motor storage program so users don’t have to worry about storing their motors on their own. When it comes to storing electric motors, there are several important components to consider. Specifically, proper environment and bearing main...

Professionals across many industries understand the value of preventative maintenance and the importance of having a good working knowledge of the electric motors being used in manufacturing operations. In fact, electric motors are one of the most vital pieces of equipment in a manufacturing process, driving virtually all production equipment and processes. preventing motor failure For these reasons, it’s critical for businesses to understand the importance of preventing motor failure a...

Balance for an electric motor refers to ensuring that the rotating parts of the motor, such as the rotor and the shaft, are evenly distributed in weight and properly aligned. When a motor is balanced, it means that these parts spin smoothly and evenly, without causing any unnecessary vibration or wobbling. Balancing the electric motors during a repair is important for several reasons: Reducing Vibration: When an electric motor is out of balance, it can cause excessive vibration, which can d...

The plastic industry relies on injection molding machines to produce part after part. To endure the high demand, the motors on injection molding machines are manufactured to withstand extreme environments. The motors are water-cooled and are unique compared to a standard motor. When repairing these motors, users should consider how to repair shop strips the motor of its coils, how it is rewound and how the windings are varnished. Burnout Oven method The stripping methods used by standard moto...

When it comes to electric motor repair, precision is everything. The smallest miscalculation in machining tolerances or assembly can lead to catastrophic failures, drastically shortening the life of a motor. They recently encountered a case that perfectly illustrates this point: a customer’s motor showed clear signs of incorrect bearing housing tolerance, leading to internal bearing preload. While this may seem like a minor oversight, the resulting damage was anything but small. The Issu...

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 makes the windings more mechanically rigid. What are the different types of varnishing methods? There are four types of varnishing methods that they will describe below: Dip and Bake Epoxy Varnishing, Trickle Varnishing, Vacuum Pressure Impregnation, and Ultra-Sealed Winding. Dip and Bake Varnishing Technique Dip...

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 the Common Belt Problems blog, improper belt tension is a pioneering cause of issues in the belt drive systems. There are two scenarios for improper belt tensioning: too tight and too loose. When a v-belt is too tight: If a belt is too tight in a system...

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 at 60 Hz, it can change the frequency to 20 Hz, resulting in a slower rotation of the motor. Different Parts of a Variable Frequency Drive The t...

Features of the Leeson TEAO Tower Motors There are many features of the Leeson TEAO Tower Motors that make an exceptional cooling tower motor, including: Designed for sha...

Dreisilker is excited to announce the launch of a new Enterprise Resource Planning (ERP) software hosted by Rocket Software. The new ERP was launched on Saturday, April 7th and is a cloud-based platform. “When considering a new ERP system, we thought about how we can improve our processes so that our customers have a better experience with Dreisilker,” said Lynn Dreisilker, Marketing and Branch Operations Manager. Integrate the ERP with e-commerce platform Lynn Dreisilker adds, &l...

Motors can be damaged by excess heat caused by current flow when there are overload conditions. Some examples include a locked shaft, too many systems on a circuit, and the power supply single phasing on a three-phase circuit. Installing overload relays in the applications can protect the motors. Why are Overload Relays needed? When a motor starts, it typically requires six times the full-load current rating. After the motor ramps up to operating speed, the current drops off. Motors are design...

Motors and generators are often mounted in a location that makes them susceptible to contamination. Over time, these contaminants cause major problems that can lead to bearing or complete motor failure. In this article, they’re going to outline four common scenarios in which contamination impacts motors and generators. They’re also going to provide solutions to keep the bearings and motors clean and free from contamination. Breakdown of bearing lubrication or damage to the bearing...
