Motor voltage higher than battery voltage

In summary, connecting a 36v electric motor to a 24v battery may cause the motor to run slower and with lower torque. However, in the case of a 24v battery on a 36v motor, it should run fine. It is important to note that running a motor at higher than its rated voltage can damage the battery and overheat the motor. Throttles are typically used to control the speed of a DC motor by adjusting the voltage. In the case of an AC motor, it may not work in the same way.

what happens if you connect a 36v electric motor to a 24v battery? Is that going to ruin the battery/motor?

It'll probably just run slow

A typical PM DC motor will run slower and at lower torque at lower voltage and may not turn at all. If it stalls it may drain the battery and damage it. However your example of 24V battery on 36V motor should run fine. Typically the voltage rating of the motor is the max for continuous use. DC motors are often used as variable speed motors where you lower the voltage to reduce speed. (AC motors don't work that way though.)

Of course the reverse case can be a concern for your battery and motor, i.e. running a motor at higher than rated voltage will draw a lot of current, possibly damaging the battery and over heat the motor burning it out if run continuously.

ok so basically I should be fine as long as I only throttle up to 24 volts?
do throttles usually increase/decrease the voltage or current?

To Jaredmt...

Just for fun, what do you think would happen if you hooked up that battery up to a 36 volt AC motor?

What does it mean if the motor voltage is higher than the battery voltage?

This means that the motor is receiving more voltage than what the battery is able to provide.

Is it safe to have a motor voltage higher than the battery voltage?

No, it is not safe as it can cause damage to the motor and other components of the circuit. It can also lead to overheating and potential fire hazards.

How can the motor voltage be higher than the battery voltage?

This can happen if there is a voltage booster or converter in the circuit that increases the voltage going to the motor. It can also occur if there is a malfunction or error in the circuit.

Can a motor still function properly with a higher voltage than the battery?

It is possible for a motor to function with a slightly higher voltage than the battery, but it may result in reduced lifespan and efficiency. It is important to ensure that the motor is receiving the correct voltage for optimal performance.

How can I prevent the motor voltage from being higher than the battery voltage?

To prevent this, it is important to use the correct battery and voltage for the motor. It is also recommended to use voltage regulators or limiters in the circuit to prevent any fluctuations in voltage. Regular maintenance and monitoring of the circuit can also help prevent this issue.
