As a content writer at HEM Motor, she has spent nearly six years preparing content on electric motors used in pump, fan and exhaust applications. From centrifugal and submersible pumps to exhaust and ventilation fans, she explains in plain language how motor selection relates to flow rate, pressure and speed parameters. With real field examples she shows how correct motor selection affects system efficiency and uninterrupted operation in water and wastewater treatment plants, HVAC and ventilation systems, and agricultural irrigation. She also touches on the control and energy advantages that variable speed drives bring to pump and fan systems. Drawing on the experience of the manufacturing and technical teams who know field applications well, she aims to provide practical, accurate and reliable information that guides readers in selecting the motor suited to their application.
Getting two different speeds from a single motor is a direct purchasing advantage for many machine builders and plant operators. Dual-speed (Dahlander) asynchronous motors let you ... More Details
Mount the same reducer horizontally, vertically or inverted under a ceiling; the housing is the same, but the behaviour of the oil inside it changes completely. The reducer mountin... More Details
In a lifting or conveyor application, the most critical question is often this: when the motor stops, will the load run back? One of the most valuable features of worm gear reducer... More Details
As efficiency classes rise, businesses rightly wonder about the next step: IE5, which comes after IE4, and its best-known technology, synchronous reluctance (SynRM) motors. This ar... More Details
The electric motor that drives a centrifugal pump is the heart of the system; but selecting the right motor is not simply a matter of looking at the pump's nameplate and ordering t... More Details
When buying a three-phase AC asynchronous motor, most businesses select the power and speed correctly; but when the motor is installed on site and started for the first time, unexp... More Details
Your worm gear reducer is ready, you have selected the output speed and the ratio; all that remains is to mount the right electric motor onto the reducer housing. And this is exact... More Details
In a period where energy costs take up an ever larger share of operating budgets every year, motor purchasing decisions are no longer made on power and speed alone. The efficiency ... More Details
The most common mistake when buying a reducer is making the decision by looking only at the purchase price. Yet the real cost of a geared motor to an operation is not the figure on... More Details
When an electric motor fails at a mine site, it is nothing like a breakdown in a city workshop. On a facility set up hours away from the nearest supplier, often in mountainous and ... More Details
When a need arises for a low-speed, high-torque drive, the buyer has two roads ahead: buying the motor and reducer as a single body combined at the factory (a geared motor), or buy... More Details
An electric motor is the common language of industry in any country; however, taking delivery of that motor on time, in the right configuration, and through a smooth customs proces... More Details
