    · It runs cooler

    The G3718V whisper torque motor incorporates a heat-sink design within the stator laminations to allow for passive cooling. When your motor operates cooler, you can increase power to gain more torque without overheating, or you can save energy and still perform at an optimal performance. This is what makes all G-series steppers from Lin so unique: the motors are green and energy efficient.

    · It's slimmer

    The G3718V is slim by design. End caps are laser welded to the stator, eliminating much wasted space in traditional stepper motor designs. This laser welding assembly eliminates the need for assembly screws to hold the motor together. This unique construction offers great length to torque ration. At only 22.8mm long, the motor produces 25 oz-in of torque. Applications can mount this motor by utilizing the 4 through holes that are designed into the stator lamination.

    · It's customizable

    If encoder feedback is needed, the sleek and slim CUI encoder is a great addition to the G3718V. The CUI incremental encoder uses a patented capacitive ASIC Technology with low power consumption. Choose from various quadrature resolutions up to 2048.
    G3718V-01 vs. Competitor

    · It's smooth, quiet, accurate, and delivers ample amount of torque

    This stepper motor is a 1.8 degree per step motor, but it is as smooth as Lin's smoothest 0.9 degree stepper. With all the know-how and technology that Lin Engineering brings, implementing key design aspects from the 0.9 line into the G3718V has created a motor that wins in both smoothness, accuracy and torque. In traditional designs, one must compromise torque for smoothness or vice versa. With the G3718V, you can still get both.
