Servo Motor

AC SERVO MOTOR

Precision, Speed, Accuracy, Throughput and Analytical functions are the design target of every control system. 





Servo motor is an electric motor designed for precision purposes most especially for position, velocity and torque control capability which makes motion/movement more accurate.

Servo motor's design unlike other synchronous motor takes advantage of feedback feature to deliver accurate motion as profiled in the program software.

Like all other motors, servo motor consist of Rotor and Stator but in addition has encoder/resolver as the feedback component while some are with or without brake system depending on applications


Other electric motor may be started directly by applying the voltage using some forms of switching devices such as contactor or switches while others may be powered with frequency inverters where there may be need for operation speed to be regulated but servo motor does not follow suit. It is being power by Servo driver or servo drive. The driver/drive contain CPU which need to be programmed with the specific application profile of the function that the motor attached to it will perform.
The Drive exchange instruction/command with the main PLC of the machine in other to command when needed. 


The servo drive may be program to provide index or step motion after the press of a push button or when a sensor senses a displacement or at the expiration of a timing sequence or following a looping operation. The drive produces pulse to provide frequency, angular or velocity control.


Servo drive contains the following contact or ports;
POWER supply voltage
IO/ANALOG external command
FEEDBACK/ENCODER
SERIAL/IP for programming
PLC interface
24V enable input supply
MOTOR TEMPERATURE
BRAKE

Methods of starting Squirrel Cage Induction Motors

METHOD OF STARTING ELECTRIC MOTOR There are several method of starting Induction Motor namely: ·      Direct on line starter commonly called DOL ·          Star Delta starter ·          Rotor resistance starter ·          Stator resistance starter ·          Forward and Reverse starter ·          Auto transformer starter ·          Frequency inverter starter .      Servo starter ( position/timing based) Before exploring the methods mentioned above, it is of higher importance to understand very well the makeup of an electric motor with emphasis on Three Phase Motor. There is virtually no process or packagining equipment that could operate in the industries without the need for motion transmissi...

PROCESS CONTROL ACTUATOR

Image
PROCESS ACTUATOR Actuators are devices that are directly connected to control device in the field to achieve control actions. It may be coil, lamp, relay, vibrator, solenoid valves, cylinders, electric motor, pump, and so on. Another name for output devices is ACTUATOR. They are powered with any of this form of energies electrical, pneumatic and or hydraulic energy. Some actuator performs action without given feedback to elements controlling them while some gives feedback about their current position or status of mechanism they are attached to. Some actuators make use of digital output signal to perform operations while some uses analogue signals to perform operation. Some makes use of only one source of energy to initiate control actions while some combines two sources of energy to initiate control actions such as pneumatic and electric power as in the case of pneumatic components . Some actuator can convert mechanical rotational motion to linear moti...
