How fast can a 72v1200w motor run?
2 Answers
72v1200w motor speed is about 60km/h to 70km/h. The following is the relevant introduction about the motor: 1. Introduction: Motor (English: Electric-machinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (old standard uses D) in the circuit, and its main function is to generate driving torque as the power source of electrical appliances or various machinery. The generator is represented by the letter G in the circuit, and its main function is to convert mechanical energy into electrical energy. 2. Classification: According to the type of working power supply, it can be divided into DC motor and AC motor. According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor. According to the starting and running mode, it can be divided into capacitor-start single-phase asynchronous motor, capacitor-run single-phase asynchronous motor, capacitor-start-run single-phase asynchronous motor and split-phase single-phase asynchronous motor. According to the purpose, it can be divided into driving motor and control motor.
As someone who frequently tinkers with electric vehicles, I've found that a 72V 1200W motor paired with a properly matched controller typically achieves speeds between 40 to 60 kilometers per hour. Controller tuning is crucial—if optimized for higher output efficiency, speeds may approach the upper limit, but performance drops with aged batteries or heavy loads. During my tests, I've consistently hit 55 km/h on windless flat roads, though speeds fall below 40 when climbing hills or carrying passengers. Regular maintenance of the motor and circuitry is essential to prevent friction losses from hampering performance. Wind resistance and road conditions also significantly impact speed—headwinds cause noticeable slowdowns. Ultimately, don't expect sustained top speeds; realistic expectations must align with actual riding conditions.
