    Good price 3000W (4hp) bldc motor operating at 48 volt, 72 volt, 96 volt, 3000rpm, 10Nm rated torque, IP65 protection grade, brushless design for very long service life. Adding brake option, matching 3 phase brushless dc motor controller and planetary gearbox/ worm gearbox are available here. ATO recommends buying a set of BLDC motors, which is an economical solution in the long run.


    • High performance and low consumption.
      3kW brushless dc motor is three phase electric motor, which especially suited for application requiring higher efficiency and power density.
    • Wide application range and good control effect.
      BLDC motor works with a matching controller (ATOTH-G) 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.
    • Wide control speed torque range.
      Brushless dc motor works with a planetary gearbox (choose inline gearbox or right angle gearbox with gear ratio from 3:1 to 200:1) 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.
    • Low noise and smooth operation.
      Brushless dc motor has no brushes, no sparks will be generated during operation, which greatly reduces friction.
    • Good protection performance and continuous duty (24/7).
      4hp 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: How Does Brushless DC Motor Drain Oil?

    Brushless DC motors bring convenience to people's work. Brushless DC motors are used to transport oil and have different delivery requirements on different occasions. How does brushless DC motor drain oil?

    1. If you want to drain all the oil form the Brushless DC motors, you can unscrew the oil plug in the lower part of the box to drain the oil.
    2. In the case of draining oil, the liquid level from the fuel tank roof height shall not be more than 30 mm, to ensure that the bearing lubrication and cooling machine. When the jack cavity volume is too large, the need for separate set attached to the tank to ensure that the minimum height of the liquid after the oil discharge is not less than 100 mm to avoid suction air.
    3. The oil shall be changed and the fuel tank and the filter shall be cleaned after the speed-adjustable hydraulic brushless DC motor run for 500h for the first time. Oil quality shall be tested by visual inspection and tests, and the oil should be changed in time when the oil quality deteriorated. Oil change must be accompanied by tank cleaning and oil filter. If there is metal shaving or water in the oil, look for the cause and troubleshoot.
    4. The bearing relies on the oil of the plunger spring in a short time when the liquid level reduces, oil tank filter and the machine oil filter are made of 230 mesh/ inch copper wire mesh, the oil filter should be regularly cleaned in order to prevent clogging, tank fluid temperature should not exceed 60℃ while using, and take appropriate measures to cool it down if necessary.

    ATO High Torque BLDC Motor Drawings & Price List


    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.

    From: Vladimir | Date: 14/12/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. Sorry, the flange of our bldc motor can only be made as shown in our dimension drawings, not IEC B5, B14.
    2. The shaft diameter of motor or planetary gearboxes cannot be changed.

    From: AYUSH | Date: 07/04/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Because the 96v 4hp 3kW brushless DC motor is a customized product, the data of each product will be somewhat different, so it is necessary to measure the phase-to-phase resistance, inductance, and torque constant after it is produced.
    Rotation direction of 4hp brushless DC motor

    I am interested in your 3kw brushless DC motor
    I want to purchase 4 motors 3kw (72V). 2 of which will be with an external brake. The rest will be controlled by the controller. I am interested in the holding torque of the motor when using the controller in the (Brake) mode without an external brake. It can be 5-10 Nm.

    Was this review helpful? Yes No (0/0)
    ATO Responded
    Our BLDC motor ATO-130WDM10030-72V, its holding torque is 10NM, and its brake is connected with the motor, which can only be controlled by the external 24V power supply alone, and the controller itself has no braking function.
