Specifications Dimensions: 55mm can diameter, 36mm can length Stator Size: Roughly 28 x 12mm (similar to 3536 can motors) Weight: 212 grams (7.5 oz, 0.47 lb) with bullet connectors KV: 900kV Voltage: 3S-6S with appropriate ESCs Power and Current: test data coming soon! Winding Resistance: 900kV ~111 milliOhms Use 8X M5 bolts, or 8X SHORT THREAD 6mm shoulder bolts for mounting to your robot frame. TIP: MAKE ABSOLUTELY SURE NOT TO USE SCREWS THAT THREAD TOO FAR IN OR YOU WILL DESTROY THE MOTOR COILS! Just Cuz Robotics RDY-5536 900kv Brushless Hubmotor Features: No circlips, belts, or set screws! Super strong, curved neodymium magnets Epoxied magnets for extra durability High-temperature copper windings 18AWG, 18 cm (~7 inch) long silicone wires rated to 200 degrees C NEW: 3X 3.5mm bullet connectors, male preinstalled on the motor, and female included for your ESCs 900 lbf dynamic load ratings Designed for use with 6mm or 1/4″ thick weapon blades. Thinner can be used with a spacer, and thicker will be fine but will be offset from center and may require longer M4 flathead clamping screws. Max recommended thickness 0.5inch or 12.7mm. Notes: Note: The first time this motor is spun up it may draw unusually high current even with no load. This is normal and seems to be a result of the big bearings and their grease needing to warm up and distribute evenly. After a couple of minutes the no load current for the motor drops significantly as the motor and bearings heat up. Warning: The outside of this motor is like a big heatsink and can get very hot! WARNING: Using standard shoulder bolts or M5 screws that are too long will destroy your motor. Shown here: LEFT short thread shoulder bolt vs RIGHT standard thread length. If you buy a normal bolt, cut the thread to protrude no more than 5mm into the motor. For best results, pair with our very own Pariah 70A ESC with AM32 firmware pre-programmed for this Hubmotor! This is a custom motor and not a conventional one so a propeller chart is a useless stat to compare this to. You should use a 50A or greater rated ESC. This has been tested and working with 70A BlHeli32 and AM32 ESCs, as well as our 35A ESC on up to 4S (though for larger than 4″ weapons we strongly recommend the Pariah 70A). Actual current draw and torque are highly dependent on your exact ESC and configuration, battery, voltage, and loading. Air resistance and tip speed for your weapon play a huge role in the current draw of your system. Even reducing speed by 20% might cut air resistance in half. ItGresa Robotics is proud to support the builder community by offering and marketing their products. Just ‘Cuz Robotics has quickly become known for both incredible product innovation and technical support for the community through their great videos.

They are extremely dangerous. Click here for a safety video. Testing a robot with an active spinning weapon should never be done while maintaining a line of sight with the robot. Ideally, you should be testing inside an enclosed box or arena with at least 1/4″ thick polycarbonate windows or top to see through, and 1/2” or thicker plywood or MDF construction. Operation (Including testing) outside of a suitable arena or test box could cause serious injury.
