Tesla makes fully electric cars meaning you don’t have to worry about an oil change or fuel cost. However, the car has some maintenance costs, such as replacing the motor. Here’s an explanation regarding the cost of replacing a Tesla motor.
Tesla motors are built to last up to a million miles when not gotten wet or shortcutted. However, the time may come when you need a replacement. Budget for about $5,000 to $ 10,000 if you have a Model S or Model Y. A used Model 3 motor costs $2,500 to $7,000.
Teslas don’t have engines but have electric motors. The motors use electricity to power the rotation of the magnetic field, which drives the vehicle’s motion. These produce minimal pollution and are more effective.
How do Tesla motors work?
Teslas don’t have an internal combustion engine but have electric motors powered by rechargeable batteries. All-wheel drive models have the motor on the front and rear axles. Rear-wheel drive (RWD) models have the motor placed on the rear axle.
Nikola Tesla invented the induction motor used in Tesla cars. The induction motor has a rotor and stator. A rotor has two conducting bars short-circuited at each edge. The stator has a three-phase AC input in the coil for producing an RMF.
Teslas have an induction motor that generates a four-pole magnetic field. A rotor in the induction motor lags the RMF and doesn’t have brushes or a permanent magnetic field. The RMF induces electric flow on the rotor bars, making them turn.
An induction motor has speed correlating with the AC power supply. Deferring the frequency of AC increases or decreases the vehicle’s speed. Apart from making Teslas have more speed, it makes them reliable and easy to control.
What Types Of Motors Does Tesla Use?
Tesla has various innovative and efficient motors developed over the years. Each has unique features and capabilities. The motors range from single on Model S and Model x. Double motors offer extra performance, and tri-motor units offer maximum power and versatility.
Here’s an overview of the types of Tesla motors, where they are used, and their features.
| Type of motor | Car model where it’s used | Motor features |
| Single motor | Model 3 standard range Long range wheel drive | One electric motor drives the rear wheels. |
| Dual motor | Model 3 long-range AWD Model S Model X | Two electric motors are for the front and the rear wheels for better traction and handling. |
| Performance Motor | Model S and Model X Performance | Upgraded version of the dual motor for higher torque and improved acceleration. |
| Plaid motor | Model S Plaid Model X Plaid | Latest and most advanced Tesla motor for higher performance and range. |
How Long Do Tesla Motors Last?
Electric car motors generally last between 15 to 20 years. The life expectancy of an electric car motor depends on factors such as installation and input power. However, it depends on whether it performs within the limits of specified values and normal operating conditions.
According to Tesla, a motor should last about 500,000 miles, although it can make up to a million miles. The motor is immortal; the bearings need replacement after 40,000 hours of operation. Windings need replacing after 1000 000 hours of operation.
The frame and rotor are essentially immortal. Electric motors don’t have friction inside, making them last a long time. The motor has only two movable parts, which last longer than an internal combustion engine. However, it must not be shorted out, catch fire, or get wet.
What Is The Cost Of Replacing A Tesla Motor?
The cost to replace the motor in a Tesla car depends on the model and the extent of the damage. Tesla designs the motors to be extremely durable, replacing them relatively rare. However, if a replacement is inevitable, you need to budget appropriately.
By February 2023, the cost of replacing the Model S and Model Y motors is from $5 000 to $10,000. On the other hand, a used Model 3 motor ranges from $2,500 to $7,000.
The price will change depending on the particular model and region where the service will occur. However, this is just an estimate, and the actual figure could be lower or higher depending on factors such as:
- Age and car condition
- The available ability of replacement parts
- Labor costs at the service center
Only Tesla-certified technicians can repair or service Tesla cars. However, some independent repair shops can work on Tesla but may lack specialized tools and equipment. So, they may not be authorized to perform particular repairs or replacements.
What Kind Of Warranty Covers Tesla Motors?
All new trade Tesla cars come with some type of warranty. You have to ensure the warranty covers the motor before initiating repairs.
Here is an overview of Tesla cars and warranties that cover the motor.
| Tesla car model | Warranty | What it covers |
| Model S | Battery and Drive Unit Warranty | -Battery pack and components for eight years or 150,000 miles, whichever comes first. – Parts, labor cost, and battery repair |
| Model 3 | Battery and Drive Unit Warranty | – Manufacturing defects but not wear and tear -Covers Model 3 Standard Range for eight years or 100,000 miles, whichever comes first. -Covers Model 3 Performance and Model 3 Long Range for eight years or 120,000 miles, whichever comes first. |
| Model X | Battery and Drive Unit Limited Warranty | -Eight years or 150,000 miles, whichever comes first. -Manufacturing defects -Damage resulting from battery fire. |
| Model Y | Battery and Drive Unit Limited Warranty | -Damage due to low battery capacity retention -Damage from battery fire -Covers eight years or 120,000 miles, whichever comes first. |
Can I Buy A Used Tesla Motor?
You can buy a used Tesla motor. However, the age and condition of the car matter. A motor from an older car will likely be exposed to wear and tear. This affects its overall performance and longevity.
There’s also a chance that the car was involved in an accident or undergone repairs. All these have an impact on the cost of the motor.
Purchasing a used Tesla motor is a huge investment. Researching and consulting a trusted technician is very important before purchasing. It ensures you get a good-quality product that will perform efficiently for many years.
Purchase a used Tesla motor from a reputable dealership or seller with a better understanding of motors. These will give you a more accurate assessment of the motor condition and performance.
You will get peace of mind knowing that you’re getting a product backed by a warranty.
Why Is The Tesla Motor So Powerful?
Teslas have an AC motor with a permanent synchronous magnet and are liquid-cooled with a variable frequency drive. Its batteries have better power transfer. It allows an incredible amount of electricity to flow in and out of the battery to deliver exceptional power to the motor.
How Big Is A Tesla Motor?
A Tesla motor is remarkably diminutive but is armed to the teeth with potent capabilities. The motor length and diameter are 9 inches or 22.86 cm each when assembled. An AWD motor, gearbox, and inverter occupy 21 53.44 cm inches of space.
Is The Tesla Motor AC Or DC?
Most Teslas have an AC motor, although some use a DC motor. It uses both. Tesla has used AC motors in Model S and Model X. However, it introduced a permanent magnetic DC motor in Model 3.
It seems like a switch since the company stopped producing Model X and S in December 2020. The switch from AC to DC motor may be a strategy to become more energy efficient to match the company values. A DC motor is more energy efficient for making better use of input energy.
Wrapping Up
Tesla makes very reliable motors that are likely to make one million miles. However, replacement may become inevitable. The cost varies by model, condition of the car, and service location. You can have the motor repaired, switched for a salvaged one, or buy a new one.
