Gearhead/Linear Head: The Role of Gearheads

The role of reducer has a lot to do with the development of motors. In the beginning, when the motor was just an AC motor that rotated, the reducer was mainly used as a transmission to change the rotation speed of the motor and also to amplify the torque. However, as motors became equipped with a speed control function, their purpose became more as amplification of torque than as changing speed.
As position and speed control became necessary, stepper and servo motors became popular, and gearheads were used for the purpose of increasing counter-inertia as well as amplifying torque, and reduce vibration of stepper motors. In addition, the high precision positioning of motors has led to the need for highly accurate gears with no backlash as a different requirement from gears for AC motors.
For these reasons, Oriental Motor has developed gearheads in each case with appropriate characteristics as needed so as not to impair the characteristics of the motor to which they are attached. Since AC motor gearheads are used continuously, primarily for transmitting power, they are designed with priority on ensuring high permissible torque, long life, noise reduction and an extensive gear ratio product line. Meanwhile, since stepper motor and servo motor gearheads are for applications requiring high precision positioning, they are designed with emphasis on high accuracy, high permissible torque, and high speed rotation (for servo motors). The following is a detailed description of these gearheads.
