3.Advantages of 4000rpm bldc motors:


A BLDC motor with three coils on the stator will have six electrical wires (two to each coil) extending from these coils. In most implementations three of these wires will be connected internally, with the three remaining wires extending from the motor body (in contrast to the two wires extending from the brushed motor described earlier). Wiring in the BLDC motor case is more complicated than simply connecting the power cell’s positive and negative terminals; we will look more closely at how these motors work in the second session of this series. Below, we conclude by looking at the advantages of by BLDC motors.


4.Applications of brushless motor:


We can expect to see BLDC motors used in a wider range of applications in the future. For example, they will probably be widely used to drive service robots—small robots that deliver services in fields other than manufacturing. One might think that stepper motors would be more suitable in this type of application, where pulses could be used to precisely control positioning. But BLDC motors are better suited to controlling the force. And with a stepper motor, holding the position of a structure such as a robot arm would require a relatively large and continuous current. With a BLDC motor, all that would be required is a current proportionate to the external force—allowing for more power-efficient control. BLDC motors may also be replacing simple brushed dc motors in golf carts and mobility carts. In addition to their better efficiency, BLDC motors can also deliver more precise control—which in turn can further extend battery life.

BLDC motors are also ideal for drones. Their ability to deliver precision control makes them especially suited for multirotor drones, where the drone’s attitude is controlled by precisely controlling the rotational speed of each rotor.

Often ask questions:

Q: What are your main products?

A: We currently produce brushed DC motors, brushed DC gear motors, planetary DC gear motors, brushless DC motors, stepper motors, AC motors and high precision planetary gearboxes. You can view the specifications of the above motors on our website and you can email us to recommend the motors required according to your specifications.

Q: How to choose the right motor?

A: If you have pictures or drawings of the motor to show us, or if you have detailed specifications such as voltage, speed, torque, motor size, motor working mode, required life and noise level, please feel free to let us know so that we can recommend A suitable motor according to your requirements.

Q: Do you have a custom service for your standard motors?

A: Yes, we can customize according to your requirements for voltage, speed, torque and shaft size/shape. If you need to solder additional wires/cables to the terminals or need to add connectors, capacitors or EMCs, we can also manufacture.

Q: Do you have a separate motor design service?

A: Yes, we would like to design the motor separately for the customer, but there may be some die development costs and design costs.

Q: What is your delivery time?

A: Generally speaking, it takes 15-30 days for our regular standard products and longer for our custom products. But we are very flexible about the delivery time, which will depend on the specific order.
