I have recently purchased a 24 volt brushless DC motor set (underwater thruster) along with its controller. Here is the link to the product.
The description says it's 1000 watt but when I tested, it consumes around 720 watts at full throttle. I have connected the controller to DIY lithium battery pack of 24 volts and 30 amperes is measured on the clamp multimeter.
Seller has no information about the original manufacturer's technical parameters about the DC motor, nor there is any sticker or label attached to the controllers about the voltage and power ratings of controller.
My findings about the motor and controller
1. Brushless Motor
After googling about the motor using part number (7822.277.297) printed on the motor it was found that this motor is specifically designed for power steering systems in cars. But I could not find the datasheet of the motor as most of the results shows the complete steering rack system and not about the specified part number.
2. The Controller
The controller has no sticker labels about the technical specifications on the heat sink aluminium box. When I opened, it has 15 mosfets which I guess 5 mosfets for each phase wire and two large capacitors of 80 volts.
I am just curious what are ratings of motor and the controller? and if I can connect the controller to a more higher voltage like 36 volts or 48 volts battery pack to draw more power?
