Product Announcement from Exlar
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. SLG gearmotors are UL Recognized.
This design offers several advantages over traditional winding designs for a more efficient and powerful motor. Built for durability, the individual segments, more robust insulation, the magnets and potting all provide a more thermally robust motor design -- a design yielding a 35 to 70% torque increase in the same package size! T-LAM motor designs have Class H insulation systems compliant with UL requirements.
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.
