How to Protect VFD Motors from Overheating and Voltage Surges

How to Protect VFD Motors from Overheating and Voltage Surges

VFD motors are a key component in several machines that support and operate well. And these motors can overheat or be damaged by an abrupt shift in electricity, which can be a big hassle. But fear not, because there are methods to prevent VFD motors from overheating and being jeopardized by voltage surge, so they can continue to function well for long period of time.

Reasons VFD motor overheats

There are several reasons a VFD motor can overheat. One frequent culprit is when the motor strains too hard for too long. Similar to how we get hot and tired after running too much, running a VFD motor at maximum speed for an extended period of time can overheat it. Another cause of overheating is when insufficient cool air is flowing around the motor to maintain the proper temperature. VFD motors need plenty of clearance and air flow to keep cool.

Taking preventative measures to avoid overheat

There are some steps you can take to protect your VFD motor from overheating. One thing you have to do, and this is important, is to ensure that the motor you choose is the correct size for what you would like it to do. Though it would seem counterproductive, using a motor that is underpowered for a big job can cause it to work harder than it should and become too hot to handle. It's also a good idea to perform periodic checks on the motor, any wear or damage can lead to overheated. These only go so far though, and you may need to fit cooling fans or heat sinks to ensure the motor stays at a suitable temperature.

Why regular maintenance is important for VFD motors

Like anything, you need to maintain VFD motors to keep them running. That means regular motor inspections to ensure everything is up to snuff, and making fixing whatever’s not as good as it should be. In gasoline models, the motor must also be kept clean and well-lubricated to counteract vibrations and allow it to run smoothly. If properly maintained, VFD motors will last longer and perform better, which can save time and money over time.

Protecting against power surges with surge protectors

When there are power surges due to spikes in electricity, voltage surges can occur, causing harm to VFD motors. Surge protectors can be used to guard against these surges. Surge protectors function by redirecting extra power from the motor and out of harm’s way. Instead, VFD motors can be protected by surge protectors, so that voltage spikes do not damage the motors they drive, ensuring uninterrupted performance.

How can VFD motors be maintained for a longer life span

Best Practices for VFD Motor Life While there is no surefire way to guarantee the life of VFD-driven motors, there are some best practices you can follow in addition to protecting and maintaining VFD motors on a regular basis. Another good tip is to never engage in rapid acceleration or deceleration, which will cause more pressure on the motor. You will also want to check the temperature of the motor from time to time to ensure that it is not getting too hot for safe operation. These tips will help VFD motors remain in good shape in the long run.
