5 Reasons to Love Brushless Servos

Brushless AC servos are commonly used for industrial motion control today, but this wasn’t always the case. Indramat solidified its place in history by introducing brushless AC servos in 1979. These brushless servo motors had several advantages over the century-old brushed motors, and they soon became the industry standard. Indramat brushless AC servos are still widely used in factories; call 479-422-0390 for Indramat servo repair, service, or support.

Less maintenance

Brushless servo motors require less maintenance because of reduced physical wear on the servo motor. These motors do not have a physical commutator. Instead, Indramat brushless motors use permanent rare earth magnets to keep the motor turning.

Longer servo life

Less wear and tear means a longer lifetime for brushless AC servo motors. This is one of the reasons why factories across the globe still use Indramat servos that were first installed 20 or 30 years ago.

Increased efficiency

Brushless servo motors operate upwards of 96% efficiency. By comparison, traditional brushed servo motors operate at 75-85% efficiency. Brushless servos also have a high torque to weight ratio. This allows for compact motor sizes and more powerful motors that take up less space.

Improved cooling

Brushless servo motors can be cooled through conduction rather than relying on airflow for cooling. This allows for innovative cooling systems and these motors less prone to heat-related errors.

Enclosed housing

Because brushless servos are cooled by conduction, they can have a completely enclosed housing. This reduces the amount of grit, grime, moisture, and other pollutants that can damage machinery and reduce the lifespan of a servo motor. A fully enclosed housing also makes these servos suitable for washdown environments.

There’s a lot to love about your Indramat brushless AC servos, so make sure that you take good care of them. Indramat products are all legacy; this means that they are no longer manufactured new. You have two main options if your servos fail. You can repair your existing unit, or you can try to track down a replacement unit in good condition.

We can assist you with either option. We have the nation’s largest supply of emergency replacement units for Indramat motion control systems, and we can arrange Indramat factory repair to restore your servos to like new condition in as little as 24 hours. All factory repaired units come back with a new factory warranty.
