SLG Series Planetary Geared Servo Motors
|
| The UL Recognized, Exlar SLG Series gearmotors offer you one of the highest power densities available in motion control. Currently the SLG gearmotors are available in three frame sizes, 60, 90 and 115 mm frames with 1, 2 or 3 stack lengths. Single and double reductions are availble in 4:1, 5:1, 10:1, 16:1, 25:1, 40:1, 50:1, and 100:1. Their unique design is especially valued in applications where weight or space is at a premium. |

Benefits of Servo Motor/Gear Reducer Combinations
Many applications require less speed and more torque than is economically available from a servo motor connected directly to the load. A gear reducer trades top end speed, which may not be required, for an increase in output torque. Optionally, SLG motors can be wound to operate at higher than conventional servo motor speeds to further optimize the design for high power and critically compact applications. |

A servo system's performance is optimal when the load inertia is similar to the motor inertia. Frequently, instability and settling time delays result if the load inertia is high, compared to the motor armature inertia. Gear reducers are the perfect solution for this common phenomenon. The reflected inertia, which is the load inertia as seen by the control system, is reduced by the square of the gear ratio when a gear reducer is employed. For example, a 5 to 1 reduction ratio provides a 25 times reduction in the reflected load inertia ratio, thus assuring stable system operation and optimal machine performance.

Planetary Gears - A Superior Choice
Through the uniform load sharing of several gears acting in concert, planetary gearheads are a very compact, reliable solution with high torque ratings, low backlash and low maintenance. Planetary gears stay well lubricated due to the mixing motion of the planet gears with the outer ring gear. A single drop of oil on one tooth will eventually get evenly redistributed over the entire gear set, which is not the case for gear reducers using non-planetary gear arrangements.
No More Clamp or Pinion Gear Problems
Add-on servo gearheads use a collar clamp to attach the pinion gear to the motor shaft which can easily be mis-aligned. By integrating our planetary gears within the motor we have eliminated all clamps, pinions and the associated problems.
No Need for a Right Angle Gear Reducer
In the past, right angle reducers were used when the shortest possible motor/gear reducer length was required. Because they use an extra set of bevel gears to make the turn, they are expensive and the extra set of gears compromises both positioning accuracy and working life.
Operates with Any Servo Drive
Feedback configurations are available for most any amplifier available on the market. Custom OEM designs are available, please call Exlar to discuss the specific requirements of your application.
Sealed Units
The standard case coating is epoxy powder coat, gray wrinkle finish. All models are greased with a synthetic lubricant containing EP (Extreme Pressure) additives suitable for gears and sealed to the IP65 standard. Viton seals assure maximum seal life and o-rings provide complete sealing of the body of the motor.
Standard Metric Dimensions
SLG flanges are designed to make retrofitting easy. They are available in 60, 90, and115 metric frame sizes with industry standard mounting dimensions.
