Бесщеточный мотор с полым ротором

Brushless Hollow Rotor Motor This homemade KV220/430 brushless BLDC motor with an internal hollow rotor is 3D printed. The stator has 21 stator coils and 22 rotor poles (magnets) (6x6x4 mm). The rotor uses a 40x52x7 #808 (1000808) bearing. Each stator coil has 40 turns of enameled wire with a diameter of 0.25 mm, and the windings are connected in a star or delta configuration. The stator winding diagram is taken from the Bavaria calculator: https://www.bavaria-direct.co.za/sche... Motor playlist:    • Как сделать мотор   A servo tester and a 30A ESC controller are used to control the brushless motor. The motor parts are 3D printed from ABS plastic (temperature: nozzle 240°C, table 100°C, nozzle diameter 0.4 mm, infill 50%).
