3. Brushless DC Motor and Gearbox Customization

Q: We are looking forward to buying your 1kW BLDC motor with 48V (ATO-BLDC-1000R3), and have the following inquiries please:

1. Can this motor be ordered with a double-extended shaft (e.g. the shaft extends from the back of the motor - like used for an electric brake application, but without the brake)?
2. Can the 30:1 ratio worm gearbox for this motor be used with the output shaft from the gearbox pointed in a vertical direction?
3. Can the 30:1 worm gearbox be ordered separately, without the motor?

A:

1. Yes, this motor can be ordered with a double-extended shaft, the output shafts at both ends are the same size, or different sizes, just better to provide us the right drawing to customize accordingly. In addition, this customized delivery time will be longer.
2. Yes, the motor and worm gearbox can be installed vertically and horizontally, just specify when ordering.
3. Yes, a 30:1 worm gearbox can be ordered separately, but it's better to tell us your motor dimensions for best matching.

4. Double Shaft of High Torque BLDC Motor With Worm Gearboxes

Q:

• Can you provide an extended double shaft of high torque BLDC motor with 2 2-worm gearboxes and with customized specs?
• For your BLDC motor brake, is it possible to use different voltage levels for the brakes, 48V or 12V rather than 24V DC?
• Can your BLDC motor run 24 hours in 6 mounts without stopping? And what is its service life?

A:

1. Yes, sure. Just indicate your detailed specs.
2. The brake is 24VDC only, cannot be 48VDC or 12VDC.
3. As long as the temperature of the motor is below 40 degrees at running, there is no problem of continuous operation for 6 months. (Note: If the motor load is too large, it will cause the current to increase, causing the temperature to rise), and the service life is more than 10,000 hours.

5. Connecting BLDC Motor Controller to Arduino

Q: For your ATO-BLDC-KBL Series BLDC Motor Controller, does it connect directly to an Arduino? Or will we need a separate connection to connect to the Arduino?
A: 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.

6. BLDC Motor Controller for External 0-5V Source

Q: Is the 0-5V speed circuit isolated for your BLDC motor controller? In other words, my control circuit requires that my 0-5V speed reference be sourced not from the 5V controller but from my battery source. I will connect the 0V of my battery source to the COM on the controller. My reference voltage will connect to the reference input on the controller. I will NOT use the 5V source voltage on the controller.
A: Yes, you can use the battery voltage to provide 0-5V without using the controller's +5V, connect the 0V of the battery power to the COM on the controller, and connect the positive terminal of the battery to the SV of the controller.

7. Brushless DC Motor Torque Capability

Q: Does your BLDC motor generate stall torque? Like, it can hold with external torque applied to it? Can it produce a reliable torque in the stall and while being back-driven?
A: Unfortunately, our BLDC motor doesn't support producing a reliable and controllable torque in the stall while being back-driven, also, the torque is not constant and it can't be controlled.

8. BLDC Motors for AGV Application

Q: We want one of your BLDC motors to be used in our AGV application (automatic guided vehicle), what do you recommend?
A: We need to know about the following, so can recommend the most suited BLDC motor:

• What is the required motor power capacity, rated voltage, and output speed?
• What is the wheel diameter?
• How many motors are needed for an AGV?
• Does the motor need to climb, what is the slope?
• Do you need synchronous control?
• Will you install wheels or track wheels?

9. Vehicle Transport Robot Motor & Controller

Q: We are currently working on a vehicle transport robot that requires a 25-hp motor to operate correctly, which will power the whole vehicle. The peak power consumption will happen when the robot goes up a 15° ramp for no more than 20 meters at 10 km/h. We selected the ATO-180WDM50030-96 since it outputs 20hp nominal and we were wondering how long the motor will sustain a 25hp load with it and if it will damage the engine. On the other hand, we wanted to evaluate which inputs and functions the motor controller unit includes to evaluate the required connections, circuits and sensors.
A:

1. If the motor is not overloaded and has good ventilation and heat dissipation, it can be used continuously for 24 hours. When the motor is overloaded 1.2 times, it can be used for about half an hour.
2. Regarding whether the engine is damaged, our motors can withstand up to 1.2 times the load. You can provide us with the wiring diagram of the system for further confirmation.
3. For the motor controller function, please refer to the instruction manual of the accessory.

10. 500W BLDC Motor for Aircraft  

Q: I’m building a tug for my aircraft which will tow the aircraft at slow speeds. The aircraft weighs about 3000 pounds maximum weight. I’m thinking a 500W BLDC motor with a 15:1 gearbox ratio might be about right and was wondering if you had any suggestions.
A: You need to calculate how much torque and RPM the tug will need when towing the aircraft at low speeds. This way can the power, output torque, voltage, speed and other relative parameters of the motor be determined, so we can recommend a suitable motor.

11. Brushless DC Motor Direction and Heating

Q: Do your high torque BLDC motors rotate at full speed and power in both CW direction and CCW direction? Or is one direction better than the other? As I am using two motors to drive a remote control tank and one motor is heating up a lot more than the other. One motor is spinning CW and the other is spinning CCW. Any help or advice would be greatly appreciated.
A: Yes, our high torque motor spins and gets power at full speed in both CW and CCW directions. Is the load capacity of this motor drive a remote control tank the same in both directions? In other words, is the hotter motor driving a higher capacity load? If the motor is more prone to heat, please pay attention to ventilation and heat dissipation.

12. TH-G Motor Controller CAN Communication

Q: I am trying to use the ATO-BLDC-KBL motor controller using CAN commands. I am not getting any response from the motor even though I am sending commands to it. Do I need to wire anything other than the CAN pins for the motor controller to function? I am sending the following command: 1801E5D0, F4 01 96 01 00 00 00 00
A: To better solve your problem,

• Please let us know if there is any feedback when using CAN. Try changing 96 to 00.
• Please take a picture of the model information on the back cover of the driver and provide us with a photo for verification.
• It would be better if you could take pictures or videos to show any feedback.

2. How to Use Controller to Reverse and Stop the BLDC Motor?

The following video shows you how to use a Brushless DC motor controller to connect an external potentiometer to adjust the speed of the motor, naturally stop the motor, and control the forward or reverse direction of the motor.

In many cases, we cannot control the speed directly through the controller, so an external potentiometer is a good choice. Likewise, we can stop the motor or rotate the motor in the opposite direction without getting close to the controller.
