Frequently asked questions about BLDC motors
What is a BLDC motor?
A BLDC motor (brushless DC motor) is a brushless DC motor with electronic commutation. In contrast to classic DC motors, it works without brushes, which makes it particularly low-maintenance. Thanks to its design, it offers high energy efficiency, a long service life and quiet operation.
How does a BLDC motor work?
The motor’s stator generates a rotating magnetic field via electronic control, which sets the permanent magnet rotor in motion. Sensors detect the rotor position and precisely adjust the power supply to the respective position – resulting in a smooth, efficient drive.
Which protection class do I need?
The choice of protection class depends heavily on the environment:
– IP40: For dry indoor areas without moisture or dust exposure.
– IP65: For industrial applications where the motor must be protected against dust and water jets.
– IP67: For short-term immersion or high moisture exposure.
What are the advantages of BLDC motors?
– Long service life due to elimination of mechanical brushes
– Low maintenance costs
– Outstanding energy efficiency
– High torque density
– Compact design
– Quiet operation
– Precise speed control
Where are BLDC motors used?
BLDC motors are used in many areas:
– Automated guided vehicles (AGVs)
– Power tools
– Household appliances
– Medical technology
– Pumps and fans
– Automotive industry (e.g. electric power steering, air conditioning systems)
How is a BLDC motor controlled?
A BLDC motor requires an electronic control system (controller) that controls the motor current based on the rotor position. This is done either via Hall sensors or sensorless via the detection of the counter-EMF (electromotive force).
What is the difference between BLDC and DC motors?
– DC motors have brushes and wear out more quickly
– BLDC motors are maintenance-free, more durable and more efficient
– The speed control of BLDC motors is more precise and quieter
Are there sensorless BLDC motors?
Yes, sensorless variants use the feedback from the counter-EMF to determine the position. This reduces costs and simplifies the system – however, they are less accurate at low speeds.
Can a BLDC motor run in reverse?
Yes, the direction of rotation of a BLDC motor can be reversed via the control unit. This is important for applications with a change of direction or reversing.
What is the typical service life of a BLDC motor?
Depending on the area of application and load, BLDC motors can achieve a service life of 20,000 to over 50,000 operating hours – significantly more than conventional DC motors with brushes.
