The discussion centers on the feasibility of using a 180 horsepower electric motor in a car, specifically exploring options for AC and DC motors. The Tesla Roadster features a 3-Phase Alternating Current Induction Motor that delivers 288 peak horsepower and operates at 375 volts with a maximum current of 900 amps. To achieve 180 horsepower, a motor with an output of approximately 135 kW is required, translating to a need for higher power to effectively operate the motor. The calculations indicate that the power requirements for such motors can be substantial, potentially reaching 550 kW under certain conditions.
PREREQUISITESAutomotive engineers, electric vehicle designers, and anyone interested in the integration of high-power electric motors in vehicle applications.
QAT said:The first question, is their any electric motor (ac/dc) that has 180 horsepower and can fit comfortabley in a car. Second question, (if no for the first question disregard this one) how much power would be needed to power it, amps and voltage.
The Roadster is powered by a 3-Phase Alternating Current Induction Motor. Small, but strong, the motor weighs just over 115 pounds. 375 volts push up to 900 Amps of current into the motor to create magnetic fields. It delivers 288 peak horsepower and 295 lbs-ft of torque at the driver's command. At top speed, the motor is spinning at 14,000 revolutions per minute.
