The motor diameter 126.5MM, a large torque, and a smooth speed regulation. It can be used as a general power direct drive without a reduction gear to improve efficiency. The core component is supported by metal, and the rotor bracket is made of engineering plastic as the support frame, which can meet the low requirements. When there is a small demand for power, or as a demonstration of a teaching model.
This motor is a permanent-magnet three-phase DC brushless motor, and it can be used only if a matched brushless motor driver is purchased. At the same time, it is also a generator, which can output three-phase AC power when receiving external force transmission (such as hydraulic, wind, hand crank, treadmill, Stirling engine, etc.), and can be converted into DC use by adding a three-phase rectifier bridge. Charge the battery. Because the motor has a simple structure, easy disassembly and assembly, flexible installation and fixation methods, multiple coaxial connections can be obtained in parallel to obtain multiple power output, and the shaft can be replaced by any length on its own. It is a preliminary product development, DIY production of various model toys, small The best choice for generators.
This product uses a standard magnetic circuit design. The rotor steel ring is a magnet and can form a magnetic flux circuit with the stator core to make full use of electromagnetic torque. Plus excellent pole slot combination, the magnetic potential utilization rate is high, and the cogging torque is small. Maximize the comprehensive performance of the motor. The stator punching plate adopts Hall embedded positioning slot design, so that the Hall element can accurately measure the rotor position, make the three-phase winding brushless commutation more accurate, and ensure the motor's forward and reverse performance is consistent. Special Note: This product has not been carefully corrected for dynamic balance, and the motor may vibrate in the high-speed range. Try to reduce the vibration value when shipping, but the specific value cannot be guaranteed.
This product is a hollow shaft design, and 8 M3 screws can be installed on the front and back of the shaft end, which is convenient for adding a rotary encoder (magnetic encoder, grating encoder, etc.) to the motor, and then it can be applied to CNC machine tools with a servo drive. , Robotic arms and other intelligent applications. If the rotary encoder is not added, the motor has its own Hall sensor, which can be directly driven by a common sensorless brushless driver.
This motor adopts domestic bearings. If the rotation speed is too high (greater than 3,000 rpm), it may cause bearing heat. Please pay close attention to its temperature rise.
The driver matched with this motor can directly adjust the speed (the potentiometer 0~5V analog voltage or PWM signal speed regulation), thanks to its multi-slot multi-pole structure and Hall sensor, to ensure that it can also run normally at low speed conditions .
