Question: How is a servo motor different from a regular motor?

What makes a motor a servo motor?

A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loop system providing torque and velocity as commanded from a servo controller utilizing a feedback device to close the loop.

What is difference between servo motor and spindle motor?

I would think your difference is because the axis servo (synchronous) motor has permanent magnets which have an effect on the motor rotation even when no voltage is being applied whereas the spindle motor (asynchronous) has no permanent magnets and relies on the rotating field to produce a magnetic field.

What are the applications of servo motor?

They are small in size but pack a big punch and are very energy-efficient. These features allow them to be used to operate remote-controlled or radio-controlled toy cars, robots and airplanes. Servo motors are also used in industrial applications, robotics, in-line manufacturing, pharmaceutics and food services.

When would you use a servo motor?

Servos are especially helpful for radio-controlled airplanes to position control surfaces. But servos are mostly used for industrial purposes. Important industries such as robotics, pharmaceutics, food services and in-line manufacturing also make use of servos.

Why are servo motors so expensive?

A Servo Motor and drive solution is more expensive than a stepper motor solution because of the complex encoder feedback device found in the servo drive hardware and the algorithms required to drive the motor with the appropriate control signals.

Which is more accurate stepper or servo?

To summarize, stepper motors are good solutions for applications with low speed, low acceleration, and low accuracy requirements. … Servo motors are a better choice for systems requiring high speed, high acceleration, and high accuracy. The trade-off is a higher cost and complexity.

What type of motor is a spindle motor?

A spindle motor is a small, high-precision, high-reliability electric motor that is used to rotate the shaft, or spindle, on which the platters are mounted in a hard disk drive (HDD).
