Motor operation in hot and cold climates

Overheating is one of the most common ways to damage electronic and electrical machines. This is especially true for electric motors. The temperature range of a motor is clearly defined by the instruction manual and the motor nameplate. An ambient operating temperature range of -20° C to 40° C is most common for general purpose […]

Motor enclosures: The passive part with a crucial role

Electric motors have innumerable applications. The simple, efficient, reliable conversion from electric power to kinetic rotary output is invaluable to modern industry. Yet, application suitability is often determined by a passive mechanical part – the motor enclosure. Factors such as ambient explosive gas, weather conditions or environmental contaminants like dust, debris, moisture or chemicals are […]

Understanding variable frequency drives and applications

Variable frequency drives (VFDs) are solid-state electronic motor controllers that efficiently meet varying process requirements by adjusting the frequency and voltage of power supplied to an alternating current (AC) motor, enabling it to operate over a wide speed range. External sensors monitor flow, liquid levels or pressure and then transmit a feedback signal to a […]

Regular maintenance and wiring inspection are crucial for VFD health and longevity

A regular maintenance schedule is important to keep a variable frequency drive (VFD) operating efficiently and effectively. Cost-effective maintenance starts early in the design phase by ensuring that the right type of VFD is selected for the job. For outdoor applications such as oil and gas operations, irrigation, wastewater treatment and mineral extraction, the correct […]

What is an explosion proof electric motor?

Preventive safety requires careful selection of equipment, particularly electric motors, in dangerous oil and gas recovery, chemical and petroleum refinery and mining environments. Motors can create an explosion by one of two means: A motor surface gets so hot during operation that it ignites a vapor, gas or dust A single arc from a motor […]

Key considerations for selecting optimal conveyor drive components for bulk material conveyor systems

Selecting proper drive components for a bulk material conveyance system can go a long way toward maintaining optimal performance and extending the lifetime of equipment. The severity of an application as determined by factors such as hours of operation, shock loading and cycles are some of the criteria designers must consider when making conveyor drive […]

Simple Guidelines for Efficient Farm Duty Motors

Motors for agricultural applications need to be durable and reliable in the harshest conditions, and the time it takes to install or repair a farm duty motor can be significant. As a result, the initial price point is just one factor when evaluating the overall cost of a motor. Maintenance and upkeep challenges also need […]

Gear Reducers: The Basics

What is a Gear Reducer, anyway? In the world of mechanical power transmission, there are a lot of moving parts, and things can get complicated quickly. A very important part of these systems are gearboxes – compound machines that transfer power from a prime mover to a load. Gear reducers are the primary focus of […]

Rotor Rotation of AC Motors

As mentioned in our previous article on rotating magnetic fields of AC motors, this article will review how a magnetic field actually creates torque and rotates the load. If you’re new to this series, you may want to start at our article on the construction of AC motors. Otherwise, we’ll jump right into rotor rotation. […]

Rotating Magnetic Fields & AC Motor Operation

To understand AC motor operation, it’s important to look into the development of rotating magnetic fields. These magnetic fields follow the fundamentals of electromagnetism to rotate the shaft of an AC motor. Let’s take a closer look at an electric motor stator. Remember that the construction of an AC motor stator is a hollow cylinder […]

About AC Motor Magnetism & Electromagnetism

AC motor magnetism and electromagnetism are a critical part of overall operation. All magnets attract and hold metals such as iron and steel. A magnet will maintain a “north-south” position if it’s free to move (like the needle on a compass). Magnetic Lines of Flux An invisible force, known as “lines of flux,” allows magnets […]
