An automated device which is controlled to work properly because of the feedback from something in a control system is known as a servo, such as amplifiers that control the speed of servo motors. Such kind of servo motor which is best in its application is the Mitsubishi Servo Motor.
The servo motor speed is controlled by the servo amplifier by receiving feedback from the motor encoder. And, it is used in position control work or jobs that require very high-resolution positioning by using a Programmable Logic Controller (PLC) that supports the Motion Controller and, this type of model is MR-J4.
Types Of Servo Motors Of Mitsubishi
There are many Mitsubishi Servo Motors to date and some of the latest motors are as follows:
- HG Series: This type of servo motor has very high-speed motors with a medium moment of inertia. In this latest technology, servo motors the speed sensor has been improved.
- HF Series: It is also based on the medium moment of inertia. This type of servo motor has high accuracy with very quick acceleration.
- HF-KP Series: It is that kind of motor that requires high-speed positioning for its suitability for an auxiliary axis with a low moment of inertia.
- LM-F Series: It is a linear servo motor which has enabled the motor industry to use it in clean environments because there are no ball screws so grease use gets restricted.
- TM-RB Series: It is combined with a high gain control system to provide quick positioning and high acceleration, run by direct drive servo motor with high-torque direct-drive.
Working Principles Of A Servo Motor
Mitsubishi Servo Motors consists of a DC motor, a position sensor, a gear set-up, and a control circuit. It gets power from a battery and runs at low torque and very high speed. The assembly of gear and shaft with lower speed connected with DC motor to run at high speed and low torque. The information is feed to the control circuit after the sensor senses the position of the shaft from its particular position. A Pulse Width Modulation Technique is used for controlling the position to control the servo motor. The pulse emitted from the controlling system determines the angular position. The advantages of servo motors are that on detection of heavy load on the motor, the driver needs to increase current to the coil, to rotate the motor, giving no out-of-step condition of the motor.
