When selecting a motor, horsepower and voltage are critical factors to consider. Horsepower relates to the power output of the motor; it must match the application's requirements to ensure efficient operation. If the motor lacks sufficient horsepower, it may struggle under load, leading to performance issues or premature failure.

Voltage is equally important, as it must be compatible with the electrical supply available. Using a motor with the wrong voltage rating can result in ineffective power usage and can cause damage to the motor or the connected system.

While other factors such as durability, cost, size, and aesthetics may play a role in the overall decision-making process, they are secondary to the motor's fundamental operating characteristics of horsepower and voltage. Focusing on these two primary specifications ensures that the motor will perform effectively and reliably within the intended application.
