Brushless electric motor HPM5000B (BLDC) 5000 W 72V with liquid cooling The motor belongs to the class of valve motors: non-contact DC motor with excitation from permanent magnets (neodymium-iron-boron). The rotor position is determined at any time by 3 Hall sensors (for touch controllers). Temperature sensors are installed to control overheating. Application: Electric cars, electric motorcycles, electric tricycles, electric golf carts, electric boats, etc. Features: Compact design, waterproof. Stainless steel shaft, liquid cooled. To operate the motor from a DC source, a controller of appropriate power is required. To control the speed of rotation of the BLDC motor shaft, you need a gas pedal or a throttle stick.
