In motor terms, what does torque refer to?

Torque in motor terms specifically refers to the rotational force that a motor generates. This force is a crucial aspect of motor performance, as it determines the motor's ability to perform work. Torque is what allows a motor to start moving a load and to maintain its motion against resistance.

When a motor operates, it creates a twisting force on the output shaft, which translates into linear movement depending on the mechanical configuration it drives. The amount of torque produced by a motor is influenced by factors such as its design, the current supplied, and the speed at which it operates. Understanding torque is essential for selecting the right motor for a specific application, as it impacts the motor's overall efficiency and performance in various tasks.

In contrast, the other options refer to different properties of a motor. Speed pertains to how fast the motor operates, electrical power input relates to the amount of electrical energy consumed, and mechanical efficiency measures how effectively the motor converts electrical power into mechanical movement. Each of these plays a role in motor operation, but they do not define torque itself.
