Motor Application
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.
