Are These Advantages and Disadvantages of Industrial Electric Motors Important to You?

Scale - Advantage and Disadvantages

According to Allied Market Research, the global electric motor market is projected to reach $136.4 billion by 2025, growing at a compound annual growth rate of 4.5%.

As with any expanding market, there comes the need to service that growth.  At RSAW we focus on large and small industrial electric motor repair, storage and sales to keep our customer’s operations and factories running smoothly and eliminating downtime. 

Today’s post looks at a few advantages and disadvantages of some common motor types that we service, store and sell, and why having the right solutions partner can make a real economic difference. 

Let’s take a quick look…
  • When it comes to self-commutated motors, at RSAW we focus on Brushed DC Motors which offer the advantages of simple speed control and low initial cost.  Disadvantages can include higher maintenance (especially brushes), a medium lifespan, and costly commutator and brushes.  What this means is that inspection and repair expertise can play an important role in lowering your total cost of ownership and increasing the economic value of your asset.
  • In the area of AC Asynchronous motors, you will find us working on AC polyphase squirrel-cage or wound-rotor induction motors (SCIM or WRIM) which offer several advantages including self-starting, low cost, robustness, and reliability. Disadvantages can include the need for a high starting current, as well as lower efficiency due to a need for magnetization.  It is important that your service and support protocols anticipate these considerations, and others, to maximize performance and reliability.
  • And finally, when it comes to AC Synchronous motors we specialize in Wound-Rotor Synchronous Motors (WRSM) which offer advantages of synchronous speed, an inherently more efficient induction motor, and a low power factor.  Disadvantages can include higher investment cost, which means that proper maintenance, repair, and storage can be critical factors to consider when attempting to maximize the up-time and operational lifespan of your motor and boost ROI.
