    1. High performance and low consumption
      400W BLDC 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
      Brushless DC motor works with a matching controller (ATO-BLD750) 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: Brushless Design Benefits of Brushless Motor

    The traditional traction motors are driven by a DC brush motor, but there are troubles and difficulties in maintenance due to the problem of the motor carbon brush commutator. Brush DC motor cannot be made into a closed structure, it is not suitable to apply in poor environment. However, trams are mobile devices that must withstand harsh environments and bumpy vibrations that happen to be unacceptable to brush DC motors.

    ATO DC brushless motor is applied with the control principle of permanent magnet DC brushless motor, there is no carbon brush and commutator, therefore the motor can be designed to withstand a variety of weather-tight closed-structure. The motor has no maintenance problems, and with a simple structure, it is resistant to bumps and vibrations, in order to achieve a long life.

    After applying the DC brushless motors, all the previous problems can be solved. Since there is no need for carbon brush, the motor can be made into a closed type to avoid the problem that it may face in a bad environment, the starting torque can be up to 400 ~ 600 %.


    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.

    Wiring ATO High Torque BLDC Motor With Controller

    In this video, we will show you how to connect a ATO 400W-15kW 24V/48V/72V/96V high torque brushless DC motor with the matching controller.

    How to Make Your BLDC Motor Forward and Reverse Control

    If you want your electric car to be more powerful, try using ATO high torque BLDC motor kit as the power unit. It is a good idea. Refer to the video step by step to operate, you can achieve the forward and reverse control of the brushless DC motor.

    Existing reviews of 400W Brushless DC Motor, 24V/48V, 1.3 Nm, 3000 rpm
    Need a BLDC motor to make 250kg Automated sliding door
    I need one bldc motor for 250kg sliding door. The speed of the door is 15-20cm/sec. What do you recommend?
    From: Yaseer | Date: 11/04/2024
    Was this review helpful? Yes No (0/0)
    ATO Responded
    We need to know more information such as the sliding coefficient of the system, the movement angle and the mechanical structure, etc.
    update the page for the motor
    I might want to update the page for the motor, it also shows .96Nm as the peak torque in the description. Unfortunately, it might not work for our application anymore, so does the 400w motor only have 300 watts capacity?
    what is the rated torque of the gearbox? do you have the chart of specific efficiencies?
    From: Mattew | Date: 06/11/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Sorry, this is an error in the description of our website.
    The rated torque of this 400w motor at 3000rpm is 1.27Nm, and the peak torque is 2.54Nm (but it can only last for 2-3 seconds).
    The efficiency of the turbo reducer is only about 60%. The final torque output by this 400W motor matched with the 30:1 turbo reducer is about 34Nm.

    What is the final torque output of the gearbox required by your system? What is the final speed?
    Weight of 400W brushless DC motor
    For your 1/2 hp (400W) 24V/48V 3000rpm brushless DC motor -> I want to know the weight of the motor with a gearbox reduction of 1:120?

    Need a BLDC motor for AGV application
    We want one of your BLDC motor to use in our AGV application (automatic guided vehicle), what do you recommend?
    From: Gavin | Date: 31/08/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    We need to know about the following, so can recommend the most suited motor:
    1. What is required motor power capacity, rated voltage, and output speed?
    2. What is the the wheel diameter?
    3. How many motors are needed for an AGV?
    4. Does the motor need to climb, what is the slope?
    5. Do you need synchronous control?
    6. Will you install wheels or track wheels?
    Can we control 2 BLDC motors via one controller?
    Can we control 2pcs 400W BLDC motors via one controller like an electric wheelchair?
    From: Alain | Date: 12/11/2019
    Was this review helpful? Yes No (0/0)
    ATO Responded
    No, it is better to use one controller to control one motor.
    Will order 3pcs 400W BLDC motor with gearbox
    Could you give me a weight for the 400W IP54 BLDC motor with a 20:1 gearbox with and without brake? I think this motor kit is perfect for my project, will order 3pcs after info was confirmed.
    From: Eric J | Date: 22/07/2019
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, the motor is 2.4 kg, the 20:1 gearbox is 2.7 kg, and "motor + gearbox" weight is 5.1 kg.
    Will send you detailed drawing if needed.
    Great Brushless DC Motor
    A good product from ATO, I bought this 1/2 hp (400W) 24V/48V 3000rpm brushless DC motor a week ago. I use it in a rock tumbler. It works great as both a motor and a generator.
