FASTECH

◆ Adopt SHIMPO’s high accuracy planetary gear: Ezi-SERVO PG series, FASTECH’s new Planetary Geared Step Motor unit product maximizes User’s operational convenience with integration between Closed Loop Stepping System, Ezi-SERVO and Helical Gear structure of SHIMPO’s high accuracy planetary gearbox has 3 min less Backlash.

◆ Vibration, Low Noise: Ezi-SERVO PG series, a High Precision of Helical Gear structured SHIMPO planetary gearbox developed for low vibration and extremely low noise of operation and both of single and double stage of gearboxes generates backlash less than 3 min so it would be the best solution for high accuracy of positioning.

◆ High Rigidity, High Torqu: SHIMPO Planetary Gearbox, combined with Ezi-SERVO PG series, maximized allowable torque with using Needle Roller bearing and machined body to be internal gear so it enables compact design of gearbox and maximized durability.

◆ Long Life & Maintenance Free: Ezi-SERVO PG Series is Maintenance-free product. No risk of grease leakage because of high viscosity of Anti-separation grease and it is maintenance free products because of lack of necessity for grease replacement.

◆ Resonance Minimization: Ezi-SERVO PG series by applying the planetary gearbox, gear ratio corres ponding to the overall operation speed of the stepper motor so low speed that occurs mainly in the resonance of a stepper motor can drive the motor to avoid the band itself and the system is very effective in reducing the vibration.

◆ Various Gear Ratio: Ezi-SERVO series, Unit product between a variety of gear ratio of gearbox with closed loop stepper motor, enables to generate various high torque as small capacity of stepper and also can respond under any load with flexibility

◆ Optimized Solution for Big Inertia of Rotation: Allowable load moment of inertia is proportional to the square of the gear ratio, Gearbox united Ezi-SERVO PG series enables fast positioning and smooth operation even under big intertia moment of load.
