Does a motor run faster at a higher voltage?

Yes, a motor generally runs faster at a higher voltage, as increased voltage can lead to greater current flow, resulting in higher torque and speed. However, this is contingent on the motor type; for example, in brushed DC motors, higher voltage typically increases speed, while in AC motors, the relationship may be more complex and influenced by other factors like frequency. It's essential to ensure that the motor is rated for the higher voltage to avoid damage. Always consult the manufacturer's specifications for safe operation.
