Features & Benefits
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 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 a great length to torque ratio. 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 smooth, quiet, accurate, and delivers an 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.
