DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Despite their superior qualities, brushless motors still run second to brush types in motion-control applications. Brushless systems are usually preferred, however, where their benefits outweigh their ...

The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

Electric motors can be found in most types of machinery. Here we examine some of the common myths about their selection, operation, and future. The purpose of an electric motor is to convert ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

For home appliances that require electric motors—ubiquitous products such as clothes washers, refrigerators, air conditioners and dishwashers—using an inverter circuit to drive either a brushless DC ...
