What is BLDC Motor

A BLDC Motor consists of a Stator and a Rotor. The stator creates a magnetic field which in turn will rotate the rotor consisting of magnets to power the machinery. Brushed motors on the other hand, use a series of carbon / precious metal brushes to transfer the current to the electromagnets.

BLDC Motor are essentially more reliable than a brushed motor as there are fewer parts to deal with and they are generally considered the superior of the two types. They are also considered to be the safer of the two as brushed motors can generate sparks which in certain scenarios can be hazardous.

There are two Specific Types of BLDC Motors

• Fixed RPM – This has a consistent rotational frequency for each speed setting and are used primarily for equipment which will be utilised outdoors and where speed control isn’t a requirement. Brushless motors can run in open and closed loop control.
• Variable RPM – This has a rotational frequency which can be controlled by the user. These are preferable for applications where speed control is essential.

Knowing the specific requirements of your project will make the decision easier between a brushless and brushed motor and whether a fixed or variable RPM is best.

Adavantages of BLDC Motor

There are many advantages to choosing BLDC motors for your project and these include:

• Variable Load Speed Range – Being able to control the speed of the motor means there are many more applications for which a BLDC is suitable.

• Continuous Torque Range – Electronically controlled motors like the BLDC are able to produce different torque and power outputs (Parvalux motors go up to 586 watts) making them more versatile. (Parvalux brushed motors can also provide high output torque and power. But there is more control with the brushed motors when connected through a controller.)

• Long Lifespan – A brushed motor requires direct contact between the brushes and the commutator whereas brushless motors have fewer contact parts, for example there is no friction between the brushes and commutator, therefore require less maintenance through wear and tear. This means they have a longer life span than the average DC brushed motor.

• Safer – Brushed motors have a tendency to spark due to friction with the brushes which can be a health and safety hazard in some situations. This is not a concern when using a BLDC.

• Efficient – Brushes in a brushed motor can reduce the efficiency of the motor whereas brushless motors work on 85-90% efficiency which can end up being a cost-effective option for your business.

• Compact size – Brushless motors are able to fit a lot of power, torque and speed into a small size envelope which can be advantageous as many modern precision products not only need to be powerful and reliable, but they need to fit into a very small space.

• Quiet Operation – The lack of means brushes that brushless motors are somewhat quieter than their brushed counterparts and produce less electrical noise and interference making them more suited to some industries such as medical, the food industry or other noise-sensitive industries.

• Cost Effective – Although the outlay of a brushless motor can be more expensive than a brushed alternative, over the lifespan of the motor there will be cost savings in reduced maintenance fees and machinery downtime.

• Fully Customisable – Depending on the application the BLDC is fully customisable in regard to torque and speed as well as the size envelope. The motors can be run with sensors and without sensors. Brushless motors can also have more poles than a brushed motor allowing for more precise control. Permanent magnet motors (brushed) are limited to the amount of poles they can have through the amount of brushes that can be fitted. Alternatively, there are a number of off-the-shelf options which suit a wide range of standard specifications.
