    1. High performance and low consumption
      1/2 hp brushless DC motor is three phase electric motor, which especially suited for application requiring higher efficiency and power density.
    2. Wide application range and good control effect
      BLDC motor works with a matching controller (ATO-BD50) may achieve simple to complex control, turn from CW to CCW, and meet various communication requirements (RS232, RS485, CAN, etc.). BLDC controller can be controlled through 0-5VDC analog signal to adjust the speed.
    3. Wide control speed torque range
      Brushless dc motor works with a gearbox (choose planetary gearbox with gear ratio from 4:1 to 200:1 or worm gearbox with gear ratio from 7.5:1 to 100:1) effectively reduce the motor's speed and moment of inertia to increase torque in your application, because the gearbox can control the start/stop and change speed in time.
    4. Low noise and smooth operation
      Brushless DC motor has no brushes, no sparks will be generated during operation, which greatly reduces friction.
    5. Good protection performance and continuous duty (24/7)
      400W BLDC motor kit adopts a new type of sealing device, which has good protection performance and strong adaptability to the environment, and works continuously in harsh environments such as corrosion and humidity.

    Tips: Maintenance of Brushless DC Motor

    1. Before disassembling, blow the motor surface dust with the compressed air and wipe the surface dirt thoroughly.
    2. Select the place for disassembling the motor and clean up the site environment.
    3. Be familiar with the motor structure and maintenance technical requirements.
    4. Prepare the necessary tools (including special tools) and equipment for dissembling.
    5. In order to further understand the motor running defects, do a check test before disassembling the motor. To this end, run the motor with load, and examine the various parts of the motor in detail, such as temperature, sound, vibration and so on, and test voltage, current, speed, etc., and then disconnect the load, do a no-load test alone, test the load current and no-load loss, make a record.
    6. Cut off the power, remove the motor external wiring, make a record.
    7. Use the appropriate voltage megohm meter to test motor insulation resistance. In order to be compared with the insulation resistance measured in the last inspection to determine the trend of motor insulation and insulation, insulation resistance measured at different temperatures should be converted to the same temperature, the general conversion to 75 ℃.
    8. The test absorption ratio is K. When the absorption ratio is greater than 1.33, indicating that the motor has not damp or moisture level is not serious. In order to compare with the previous data, the same absorption ratio measured at any temperature should be converted to the same temperature.


    ATO High Torque BLDC Motor Drawings & Price


    1. ATO highly recommends 48V motors because all models of 48V are in stock, the price is cheaper and the delivery time is shorter, only about 7 days.
    2. 24V/ 72V/ 96V motors are generally not in stock, need to be produced by the factory, which will cost more to start the production line and the delivery time will be longer, about 25 days.
    3. The prices in the table are just for your reference. If you want to get the latest quotation, please feel free to contact us.

    Yes, we have the stronger (aluminum body), but the price wil be higher (an option).
    Good 1/2hp brushless DC motor
    Do you have a 5hp or 5kw motor at 24v DC Brushless? What is the largest motor you have in 24VDC BLDC?
    From: Finshin | Date: 10/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Unfortunately can not provide 24VDC input option for 5kW BLDC motor, the minimum voltage is 48VDC. The max power capacity we provide based on 24VDC is 2.5 hp (1.9 kW).
    Does the motor controller connect directly to an arduino?
    Does the motor controller for the 1/2 hp (400W) 24/48/72V 2000rpm Brushless DC Motor connect directly to an arduino? Or will we need a separate connection to connect to the arduino?
    From: Steve Molk | Date: 29/04/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    The controller can be directly connected to the AVR microcontroller (arduino) to achieve brushless motor speed regulation.
    But only supports AVR microcontroller output analog voltage signal (0-5V), pulse width modulation signal, pulse signal and so on.
