Actuation Division
The UL Recognized Exlar SLG Series gearmotors offer you one of the highest power densities available in motion control. These gearmotors are available in four compact frame sizes: 60, 75, 90, and 115 mm with 1, 2, or 3 stack lengths. Single and double reductions are available in 4:1, 5:1, 10:1, 16:1, 25:1, 40:1, 50:1, and 100:1. The unique design of these gearmotors is especially valued in applications where weight or space is at a premium.
Many applications require high torque and low speed. A gear reducer in the SLG trades top-end speed for an increase in output torque. To further optimize the design, SLG motors can be wound to operate at higher than conventional servo motor speeds. The result is high power density in a compact space.
Servo systems perform optimally when load inertia is similar to motor inertia. Gear reducers offer the perfect solution. Reflected inertia—the load inertia as seen by the control system—is reduced by the square of the gear ratio. For example, a 5:1 reduction ratio reduces the reflected inertia ratio by 25 times. The result is stable system operation and optimal machine performance.

Your choice of drive will dictate the appropriate feedback device for your situation. Options for feedback type include an array of absolute, analog and incremental encoders, as well as custom feedback alternatives.
Motor Stator options are described with a 3-digit code. The first digit calls out the stack length, the second digit designates the rated bus voltage, and the third digit identifies the number of poles. Please refer to the mechanical/electrical specifications for motor torque and actuator rated force.

* Low voltage stators may be limited to less than catalog rated torque and/or speed. Please contact your local sales representative when ordering this option.
All Exlar T-LAM™ motors and actuators have a standard motor speed designator (described below). The designator represents the standard base speed of the motor for the selected bus voltage.
Please note that Exlar can manufacture its T-LAM products with specialized base speeds to exactly match your application requirements. This capability allows you to get the required torque and optimal speed for your application, while using the minimum amount of current from your amplifier.
The callout for a special speed is configured in the model number by using a two-digit code from 01 through 99. These codes represent the number, in hundreds, of rpm that is the base speed for the motor.
For example, a SLG090-010-KCGS-AB1-138-40 motor has a 4000 rpm standard winding. To specify a 3300 rpm winding, change the last two digits in the model number from 40 to 33. Similarly, to specify a 5000 rpm winding, you would change the last two digits from 40 to 50, and so on.
Note: It is not possible to produce every possible speed for each motor at each voltage. *

Special Motor Options should be listed as XM and must be approved by Exlar.*
The XL option in the model number specifies some form of lubrication other than the standard provided by Exlar®, which is Mobilith SHC220. Special lubricants include other greases, such as JAX FG-2 food grade or Mobilgrease 28. Another non-standard option is oil cooling.*
Special Feedback Options should be listed as XF and must be approved by Exlar.*
* Some options are not available with every configuration. For options or specials not listed above or for extended temperature operation, please consult Exlar Applications Engineering.
IP Ratings for Exlar Actuators
For amplifiers using peak sinusoidal ratings, multiply RMS sinusoidal Kt by 0.707 and current by 1.414.
