Why are BLDC so expensive?
Instead of an armature it has coils arranged around the inside of the stator. Due to the restricted space, the windings on most small in-runners have to be installed by hand. This is a difficult and time-consuming and job, which makes them more expensive than machine wound brushed motors.
What is a BLDC motor used for?
The most common uses of brushless DC motors in industrial engineering are motion control, linear actuators, servomotors, actuators for industrial robots, extruder drive motors and feed drives for CNC machine tools.
What BLDC stands for?

How many types of BLDC motors are there?
BLDC motors are available in three configurations: single-phase, two-phase, and three-phase. Out of these, the three-phase BLDC is the most common. All these motors are easily available in India and online shops.
What is the largest brushless DC motor?
Allied’s largest standard torque motor is the Megaflux 760 (OD 792 mm), offering a rotor through-hole size of 582 mm (22.9 inches), and a staggering 16000 Nm of intermittent peak torque at stall.
How do brushless tools work?
In a brushless motor, there are no brushes of any kind and the motor itself is turned inside out: permanent magnets are moved to the rotor, and electromagnets are connected to the stator. Then, in place of brushes, a computer, connected to high-power transistors, charges the electromagnets as the motor turns.
Are brushless tools better?
More energy-efficient. Because there are no brushes rubbing against anything, no energy is lost due to friction. That means brushless motors are more energy-efficient than brushed drills and can run on batteries for up to 50 percent longer.
What are the disadvantages of BLDC motor?
Disadvantages of brushless DC motors:
- Cost: Rare-earth permanent magnets are much more expensive than other permanent magnets, which leads to an increase in motor costs.
- Limited constant power range: A large constant power range is critical to achieving high vehicle efficiency.
Do BLDC motors use AC?
This is similar to how AC current creates a rotating magnetic field in AC motors, except that BLDC motors use DC current and electronically switches the current back and forth in each pole, simulating AC phases.
Why brushless tools are better?
Is BLDC motor efficient?
BLDC motors have reportedly hit 85 to 90 percent efficiency margins, which is higher than the standard brushed motors at 75 to 80 percent.
Do BLDC motors need inverter?
Inverter Technology (commonly found in Air Conditioners, Refrigerators and Washing Machines) also uses BLDC motors many a times. Moreover, BLDC motors have inverter to convert DC/AC and the inverter is built-in (no external inverter is required).
