7 Benefits of ATO High Torque BLDC Motor

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.

1.  Brushless DC motor has the characteristics of DC motor and its driver is also a device of frequency variation, so it is better than any frequency converter in terms of operation efficiency, low speed torque and speed accuracy. Because the ATO brushless DC motor is operated by automatic control, it does not add a starting winding to the rotor like the synchronous motor with heavy-load starting under variable frequency speed regulation, and will not produce oscillation and out-of-step when the load changes abruptly.
   
   
2. The permanent magnet of DC brushless motor mostly uses Nd-Fe-B material with high magnetic energy product. Therefore, the volume of rare earth permanent magnet ATO high torque brushless DC motor is smaller than that of three-phase asynchronous motor with the same capacity.
   
   
3. ATO brushless DC motor has high efficiency, high efficiency area, high power and torque density, power factor（COSΦ）is close to 1, and system efficiency is more than 90%. Permanent magnet brushless DC motor runs synchronously under any circumstances, AC frequency conversion motor runs at variable frequency, brushless DC motor runs at synchronous speed, and the rotor runs without copper and iron consumption.
   
   
4. ATO brushless DC motor has the advantages of good low voltage characteristics, strong torque overload characteristics, large starting torque and small starting current.
   
   
5. High torque BLDC Motor control system is simpler than asynchronous motor. With wide speed range, motor can operate in low, medium, high and large speed range.
   
   
6. Strong overloading capacity to meet the needs of vehicle protrusion and rotation blockage. On the one hand, the regenerative braking effect is good. When the car goes downhill or brakes, the motor can completely enter the generator state, charging the battery, and playing the role of electric braking, reducing the burden of mechanical braking. On the other hand, the BLDC motor is small in size, light in weight, high in specific power, and can effectively reduce weight and save space.
   
   
7. ATO BLDC motor has no mechanical commutator and adopts fully enclosed structure to prevent dust from entering the motor. It has high reliability.

See so many advantages, of course, high torque brushless DC motor will have its corresponding shortcomings, brushless DC motor must be equipped with the corresponding motor controller to work, so it will increase the cost of work, only for the motor commutator will be higher than the cost of carbon brushes, on the basis of brushless motor alone will be higher than the cost of brushless motor. In addition, if the application is a high magnetic field, the rotor of the motor itself is made by a magnet. Under the action of a high magnetic field, the magnetic field of the rotor will be changed or a part of the magnetic field will be eliminated, and the motor will not work normally.
