# What is efficiency motor?

## What is efficiency motor?

For an electric motor, efficiency is the ratio of mechanical power delivered by the motor (output) to the electrical power supplied to the motor (input). Efficiency = (Mechanical Power Output / Electrical Power Input) x 100%

### How many RPM is a 2 hp motor?

How efficient is a Tesla motor?

Tesla told Car and Driver that the motor in the Model S has gone from 80 percent efficient to 90 percent, with peak efficiency at 94 percent during the EPA test cycles. According to Tesla, if you improve motor efficiency by 8 to 10 percent, the range will improve by 15 to 18 percent.

How efficient are AC motors?

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp.

## What Motors does Tesla use?

There are two main kinds of electric motors used in electric cars, though there are many variations on those themes. Tesla, for example, uses alternating current (AC) induction motors in the Model S but uses permanent-magnet direct current (DC) motors in its Model 3.
