How do you increase the torque of a BLDC motor?
Abstract— In transportation, BLDC motors are required to have high torque. This BLDC electric motor is designed to drive an electric car. Increased torque can be done in many ways one of which is the selection of the stator material. Effect on the generated torque can be studied by replacing its stator materials.

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.
Does Tesla use brushless motors?
Today, all the hybrids are powered by DC brushless drives, with no exceptions. The only notable uses of induction drives have been the General Motors EV-1; the AC Propulsion vehicles, including the tzero; and the Tesla Roadster. Both DC brushless and induction drives use motors having similar stators.
Is brushless worth the extra money?
So if you’re someone who does a fair amount of serious projects that require a drill, going with a brushless could make a lot of sense. It’ll give you higher speeds and power, and require less maintenance. But if you’re a DIYer tackling lighter projects, you may not notice much of a difference.
What are the advantages of BLDC motor?
Seven Advantages of Brushless DC Motors
- Better speed versus torque characteristics.
- High dynamic response.
- High efficiency.
- Long operating life due to a lack of electrical and friction losses.
- Noiseless operation.
- Higher speed ranges.
How does a BLDC motor start?
One of the main concerns of running a BLDC motor is its startup operation. … There are several ways to startup a BLDC motor. One way is to use the hall sensor to detect the initial position of the rotor and then startup up the motor by energizing the 3 phases according to an energizing pattern.
