Servomotors Support Global Manufacturing Automation

If you look inside your everyday smartphones, tablets, computers and home appliances, you can see that they are made up of hundreds of different components, including electronic components, semiconductor chips, batteries and cameras etc. When manufacturing these, companies try to automate by installing industrial robots and machine tools to maintain high quality while increasing production efficiency. Servomotors are often used to enable such machines and industrial robots to perform ultra-high-speed, ultra-precise motion such as right to left or up and down.

Servomotor

Servomotors are not seen in everyday life, but they are “motors that are good at stopping at the position indicated by a comma several millimeters”, and they are important parts that must be used as power for factory automation. The positioning accuracy is such that, for example, when the motor is rotated the circumference of about 40 km, it can detect and control the error of the moving 4 mm.

Since Yaskawa invented the world’s first prototype Minertia motor in 1958, AC servo motor has led the factory automation industry with a global market share of No. 1, with cumulative shipments exceeding 20 million units. We would like to introduce what kind of industry servomotors are contributing to.

Servomotor with Various Shapes

Rotary servomotor

Rotary servomotor

The basic rotary motor consists of a rotor that rotates and a stator that supports the rotating part.

Direct drive motor

Direct drive motor

It is a motor that rotates like a rotary servomotor, and because it drives the control object directly, there is no backlash or loss of the mechanism parts, enabling high-precision control.

Linear motor/Linear slider

Linear motor/Linear slider

Directly drives the controlled object with linear movement, enabling high-speed lateral movement.

Products that Support Servomotors

encoder

Positioning sensor “encoder” supporting ultra-high speed and ultra-precision performance

When controlling the rotation speed and angle of the motor, the encoder detects minute angle information corresponding to 1/16 million of 360 degrees.

Servo amplifier

Servo amplifier that converts the output

The servo amplifier converts the output so that the motor moves in accordance with the position/speed/torque command from the host.

Machine controller, the brain of motion control

Machine controller, the brain of motion control

Machine controllers use servos and AC drives/ inverters to control various devices that perform complex motions with high speed and precision.
