What is BLDC Motor?
It is an electronically controlled motor that does not require any brushes and therefore smooth and efficient operation. It has high reliability, less maintenance and better speed control in comparison with the traditional motors. The motors are common in EVs, automation, robotics, and other industrial applications, commonly with current Brushless DC Motor Speed Control Systems.
Types of BLDC Motor
BLDC Motor suppliers in India offer various types including inner-rotor, outer-rotor, and frameless BLDC motors designed for diverse performance needs.
- By Design
- Inrunner BLDC Motor: The rotor is placed inside and stator windings are placed outside. This forms a typical motor design that can be used in high speed applications and is normally found in Brushless Drone Motor systems.
- Outrunner BLDC Motor: The rotor is rotated on the outside and the stator is stationary in the center. This design provides more torque at a low speed, which is why it is suitable in drone, automation, and other hobby applications, such as small assemblies of BLDC Hub Motors.
- Disk Rotor BLDC Motor: A special design with rotor being disk-shaped. In less common applications it is applied in small motors with motor profile requirements, particularly in applications where ironless LDC motors are desired.
- By Control Method
- Sensored BLDC Motor: Hall-effect sensors are fitted to provide accurate rotor position information and smooth starting, fine control and repeatable behaviour at a wide range of loads. These are compatible with contemporary BLDC Drivers.
- Sensorless BLDC Motor: Handles physically sensorless operations. To control the rotor position, the controller is used to measure the back-EMF, which makes it a cost efficient, lightweight, and efficient system in most applications.
- By Number of Phases
- Single-Phase BLDC Motor: Has a single stator winding and is normally operated in low-power applications like fans, small domestic appliances and small tools.
- Two-Phase BLDC Motor: Has two windings on the stator and is designed in light-duty applications such as toothbrushes, RC equipment and small motorized devices.
- Three-Phase BLDC Motor: The most popular format, which is comprised of three windings, provides more power, higher torque, and high efficiency. They are often used in industrial machines, EVs, and tools with high power, mostly in combination with sophisticated Motor Control Brushless DC systems.
Components of BLDC Motors
- Stator: This is the stationary component which has copper windings that make up the rotating magnetic field.
- Rotor: This is the rotating system with permanent magnets which tracks the magnetic field inside the stator akin to a Brushless DC electric motor design.
- Electronic Speed Controller (ESC): An electronic circuit that regulates motor commutation, speed and direction.
- Hall Effect Sensors: Position sensors used to assist the controller to locate the rotor accurately to allow smooth operation.
- Shaft: A central rod attached to the rotor passing the rotational motion to the external load.
- Bearings: Its purpose is to support the shaft and allow it to turn easily with minimal friction.
- Enclosure / Housing: It is a protective cover that protects the internal elements and is used in cooling off the internal parts.
- Back EMF Feedback (Sensorless): This is where the controller is used to feedback the generated back EMF in order to determine rotor position without rotor sensors.
- Insulation & Cooling System: Safeguards heat and electrical damages on windings and components of the motor by cooling them appropriately.
