What is the relationship between power speed and torque speed?

[Jose]

Speed and torque have an inverse relationship, while power is directly proportional to speed and torque. The formula is T=9550*P/n. Here, P represents the motor's rated (output) power in kilowatts (KW); the denominator n is the rated speed in revolutions per minute (r/min); and T is the rated torque. Below is an introduction to automotive engines: 1. Classification of engines: Based on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. 2. Principle of engines: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have higher speeds, lighter weight, lower noise, easier starting, and lower manufacturing costs; diesel engines have higher compression ratios, greater thermal efficiency, and better economic performance and emission performance compared to gasoline engines.
