Electric motors convert electrical energy into mechanical energy, which can then perform useful work. They have few moving parts, making them less prone to breakdowns and easier to maintain. They also generate instant torque, regardless of engine speed.

They are used in fans, blowers and pumps, machine tools, household appliances, power tools, and motor vehicles. They can also be reversed to act as generators for regenerative braking.

Price

The price of industrial electric motors can be quite high, especially if you need to buy them in bulk. Fortunately, you can save money by purchasing used ones instead. In addition, you can find great deals online or in catalogs that offer discounted prices.

In addition, buying used industrial electric motors can be environmentally friendly. The production of new motors uses a lot of energy. This means that buying used ones reduces your carbon footprint, which is good for the environment. If you have old, unused electric motors, bring them to Rockaway Recycling for a good price. We pay by the pound for small used electric motors, including copper coils. We also accept other scrap metals, such as lawn mowers and washing machines. Contact us for more information. We look forward to seeing you soon!

Energy efficiency

Motor-driven systems consume the largest single end use of energy in the world, and are a key opportunity for cost-effective energy efficiency savings. A better understanding of how electric motors can be made more efficient would significantly reduce electricity consumption and greenhouse gas emissions, as well as help businesses keep costs competitive.

A number of factors determine a motor’s energy efficiency, including frame size, horsepower, voltage, RPM and capacity. However, one of the biggest factors is how well a motor is designed and used. For example, using copper coils instead of aluminum ones can improve a motor’s efficiency by reducing the amount of energy lost due to conductivity differences between aluminum and copper. Other factors that improve a motor’s energy efficiency include maintaining the proper load size, choosing the right speed for the job and applying eco-driving behavior. These measures can help reduce unnecessary kilowatt usage and bring motors closer to their maximum energy efficiency levels.

Noise and vibration

The noise and vibration caused by motors can be a nuisance to people working in the same area. They can also cause damage to the equipment and even affect people's health. To avoid this, it's important to find the source of the problem and repair it before it gets worse. This is why it's best to industrial electric motors from a trusted seller that offers warranty and maintenance services.

The primary sources of noise in electric motors include electromagnetic, mechanical, and windage noise. Electromagnetic noise is caused by slippage, which is a result of the rotor field lagging behind the stator fields. This type of noise is mainly found in high-speed motors. Mechanical noise is a result of structural resonance in the motor. It can be generated by a loose stator core or poor bearings. It can also be caused by the vibration of internal components against the frame. The vibrations are transmitted to the surrounding structure and converted to airborne noise.
