*KeyFeatures *Fundamental Parameters: This brushless electric motor is powerful and efficient. Model: MY1020D, Input Voltage: 72V DC, Output Power: 3000W, Rated Current: 43A, Rated Speed: 4900 RPM, Maximum Speed: 6500 RPM, Sprocket: T8F-11 Teeth, Horsepower: 4.07 HP, Rated Torque: 849.67 oz.in / 6 N.m, Maximum Current: 65A, No-load Current: 4.0A, Peak Efficiency: 85%, Working Temperature: < 120 C / 248 . *3000W Brushless Motor: The brushless dc motor adopts a 100% copper core for low noise operation and excellent speed regulating performance. The high-precision rotor is made of high tech, finish for water resistance and high working efficiency. *Sturdy Aluminum Construction: The electric go kart motor features an aluminum alloy shell to resist heat, cold, and corrosion, which is not easy to rust. This dc electric motor is a forward and backward rotation motor so that you can switch the rotation. *Speed Controller Included: This brushless go kart motor comes with a controller to provide speed control in the desirable ranger, speed adjustment way: Potentiometer. Model: BY24WF01-B, Current: 65A, Phase Degree: 120, Conversion Efficiency: 85%, Controller Under Voltage Protection Voltage: 62V. *Multiple Application: Brushless motor is much better than the brushed motor due to its high efficiency, power frugal, low noise, long lifespan, stable operation. It is suitable for go karts, scooters, e-bike, ATV, motorized bicycle, moped, mini bikes, pocket bikes, etc. *Advantages of the brushless motor *Less electrical and electromagnetic noise *Long lifespan: No brushes to wear out, around triple lifespan as brushed motor *Low maintenance: No brushes to replace *Powerfrugal: Power consumption is 1/3 of brushed motor *High efficiency: Brushless motors are typically 85-90% efficient whereas brushed DC motors are around 75-80% efficient. ******************************************************************************************************* *Specifications Model: MY1020D Input Voltage: 72V DC Output Power: 3000W Rated Current: 43A Rated Speed: 4900 RPM Maximum Speed: 6500 RPM Sprocket: T8F-11 Teeth Horsepower: 4.07 HP Rated Torque: 849.67 oz.in / 6 N.m Maximum Current: 65A No-load Current: 4.0A Peak Efficiency: 85% Working Temperature: < 120 C / 248 Motor Net Weight: 10.36 lbs / 4.7 kg Motor Mount Bracket Size: 2.2 x 4'' / 56 102 mm Motor Dimensions(L x W x H): 6.7 x 4.2 x 4.3'' / 169 107 110 mm Controller Model: BY24WF01-B Controller Current: 65A Controller Phase Degree: 120 Controller Conversion Efficiency: 85% Controller Under Voltage Protection Voltage: 62V Load Weight: About 330.69 -440.92 lbs / 150-200 kg Power Tube: 24 PCs ******************************************************************************************************* *Pakcage Content 1 x 72V 3000W Motor 1 x Controller 1 x Multifunctional Throttle Grip 1 x Ignition Key 1 x T8F-54t Tooth 1 x T8F11 Chain 1 x Set of Mounting Screws
