Recently, ATO has released its latest brushless DC motor with 1.5 kW 48V 3000 rpm, which will improve the quality of frequently used household appliances and add new functions. Whether the juicer or a heavy vacuum cleaner, this BLDC motor can be customized by the functional requirements of these appliances. Compared with previous BLDC motors, this product has higher efficiency and service life, and can be applied in the automobile industry, electric tools and even medical industry.

In the model selection of brushless DC motor, the motor power, revolving speed, voltage, driver with reducer or not, with brake or not, installed with encoder and so on must be taken into account. Many users are unfamiliar with these parameter requirements before model selection. As a brushless DC motor supplier, ATO can help users to select the most appropriate motor model. And we will introduce a high quality and low cost brushless DC motor with 3 hp power rated,3000 RPM speed.

In order to satisfy the demand to a more strict position information, the common solution is to add incremental rotary encoder to BLDC motor. Generally speaking, in addition to Hall effect sensor, incremental encoder will also be added into the same control feedback loop system, wherein, Hall effect sensor is used for motor commutation, while encoder is used to trace the position, revolution, speed and direction more accurately. Since Hall effect sensor can only provide new position information when each Hall state changes, its precision can only reach six states of every electrical circulation. However, as to the bipolar motor, it only has six states for each mechanical circulation. Compared with the incremental encoder which can provide the resolution ratio, it is obvious that the two are required.

The brushless DC motor is a core element in the Automated Guided Vehicles (AGV) applications. The quality of the electric motor can decide the performance of the AGV. In choosing the electric motor plan, we can choose the brushed motor or the brushless DC  motor. In view of the development trend of AGV, the brushless DC electric motor is more popular.

Brushless DC motor braking is usually fast braking by motor itself. There are two simple methods. One is energy consumption braking, the other is short connection braking. Energy consumption braking consumes the motor's kinetic energy on the external braking resistance, and short connection braking consumes the motor's kinetic energy on the motor's stator winding. Obviously, energy consumption braking is more beneficial to reduce motor heating. However, the short brake does not need any hardware modification. Simple and convenient is its outstanding advantage, so it focuses on the short brake.

So can a BLDC motors be equipped with a brake? The answer is of course. Actually, the structure of BLDC motor is similar to that of many motors, which is composed of stator and rotor, it only replaces physical carbon brush with digital signal control. The principle of brake device is to clamp the stator with the lining and then stop the stator, thus realizing braking. BLDC motor is no exception. However, as the BLDC motor has a small body size, its brake devices are generally installed outside the motor. Some motors with larger body sizes, such as the three-phase asynchronous motor, install the brake device inside the motor, so it can't be distinguished clearly whether it's installed with a brake device.

The brushless DC motor not only maintains the good speed regulation performance of the traditional DC motor, but also has the advantages of no sliding contact and commutating spark, high reliability, long service life and low noise. Therefore, it is used in aerospace, CNC machine tools, robots, electric vehicles, computer peripherals and household appliances have been widely used. The following is a detailed introduction to the benefits of ATO high torque BLDC motors with 400W to 15kW power rating.

One of our customers is engaged in producing the coaxial stripping machine. The machine is fully automatic, processes of cutting, peeling, bending and torsion can be completed automatically after setting all parameters. The machine has extremely efficiency, but it also higher performance requirements for the selected BLDC motors.
This customer has contacted us at the R&D stage to select a suitable BLDC motor. As the automatic stripping machine has a small size, corresponding motor selected shall also have a small size while the power shall be from 300W to 500W, therefore, we provide a ATO-M-BLDC-80WDM01330 BLDC motor with a power range of 400W, and 24V DC voltage.

The BLDC motor applied in the electric bicycle is generally made into disc motor and installed in the hub of the wheel. The hub is connected by spoke and rim, which directly drives wheel rotation. The stator is composed of stator core, armature winding and its lead-out line, sensing element and lead-out line, stator bracket and shaft, the stator core is usually made of many pairs of poles and many slots to meet the requirements of high torque and low speed.

Torque, Speed Selection
On occasions of adjustable power supply voltage, the BLDC motor specifications whose torque and speed are close to the corresponding rated value of the product can be selected according to the actual needs, and then getting the required speed by changing the voltage. On occasions of constant power supply voltage, if there is no suitable BLDC motor for selection, the appropriate specifications can be selected according to the torque, and the voltage and speed of the product can be adjusted appropriately.
