What are the advantages and disadvantages of AC servo motor?

  • 2

Servo motor is a self-contained electrical device that can precisely drag or rotate an object with higher efficiency and can control it with the help of servomechanism. It is comprised of an appropriate motor paired to a position feedback sensor. AC servo motors are capable of handling higher current surges and likely to be used in industrial machinery.

      Servomotors are used in areas which require speed variation without the motor being overheated. The servo motor can be divided into AC and DC servo motors which have different advantages and disadvantages.

      AC servo motor advantages

      There are several advantages of AC servo motor over DC servo motors:

      • AC servo motor has more than 90% of efficiency.
      • These motor have very good speed control characteristics.
      • They generate a very low amount of heat.
      • AC servo motor has very high-speed control and high also high precision position control.
      • They can offer more torque per weight and can reduce radio frequency noise.
      • AC servo motor requires very less maintenance because of the absence of commutator.
      • The life expectancy of the AC servo motor is more.
      • AC servo motors are used in a large range of applications where position regulation is important and generally found in robots, semiconductor devices, machine tools and aircraft.

      AC servo motor disadvantages

      The major disadvantage of an AC servo motor is that their control is more complex. To determine the proportional integral derivative (PID) parameters, the driver parameter needs to be adjusted and therefore more connection is required to sustain the operation.

      At factories, mills and pressing plants, motorized machines are called upon for a vast array of critical operations. Whether you run a production line of mass-assembled products or facilitate a public utility, the operations that you oversee rely on high-powered motors that can run without fail throughout lengthy work shifts for days, months and years on end, in some cases 24/7.

      Servo motors are the mechanical components utilized for automatic control systems. The servo is a tiny component with an output shaft. The servo offers controlled precision for high-velocity, thanks to the design of the actuator. When the motor receives a signal, it accelerates the velocity of operations as dictated by the user or engineer.

      AC Servo:

      1. Depending on the precision required, you might not need a separate position sensing feedback.
      2. Very rugged, low maintenance.
      3. Might not need a separate mechanical brake using plugging.
      4. Should be lower initial cost.

      DC servo:

      1. Older system might be more familiar to maintenence staff.
      2. ?

      Stepper motor:

      1. Low cost controller.
      2. Can be capable of direct drive without separate position sensing or precision gearbox.
      3. Might not need separate mechanical brake.
      4. Rugged, low maintenance.
