High-Torque Planetary Gear Motors
Bühler Motor high-torque planetary gear motors, including series 1.61.050, 1.61.077 and modular gearheads PLG 32, PLG 42, and PLG 52, are designed to transmit superior torque within ultra-compact spatial dimensions while maintaining low torsional backlash.
The modular multi-stage architecture allows single, double, and triple stage configurations with reduction gear ratios spanning from 4:1 to 512:1 and continuous output torques reaching 30 Nm.
Internal gear trains feature precision-machined case-hardened steel pinions, high-strength engineered polymer stages in primary cascades for noise attenuation, and heavy-duty output shafts supported by dual preloaded ball bearings capable of absorbing substantial radial and axial cantilever forces.
These planetary drive units are widely deployed across industrial conveyor lines, robotic pick-and-place arms, automated packaging machinery, and valve actuators.
Bühler Motor parallel-shaft spur gear motors, including series 1.61.046, 1.61.065, 1.61.070, and 1.61.074, deliver smooth, whisper-quiet, and highly efficient torque transmission across wide reduction ratios ranging from 2.5:1 up to 1200:1.
The flat offset-shaft layout optimizes axial mounting depth, making these gear motors the preferred choice for narrow integration enclosures in automation cabinets, precision dosing machines, medical dialysis pumps, and automated vending mechanisms.
Gear trains are precision-molded and machined from a combination of alloy steel and self-lubricating engineering polyoxymethylene (POM), minimizing friction losses and eliminating periodic lubrication maintenance over the entire operating lifetime.
Coupled with DC or EC motors, they provide accurate output speeds from 0.5 to 600 RPM.
Specify output shaft speed, flange mounting geometry, gear materials, and shaft rotation direction requirements.
Worm Gear Motors and Door Actuation Systems
Bühler Motor right-angle worm gear motors, including models 1.61.073 and 1.61.111, combine smooth kinematic transmission, static self-locking holding torque, and exceptional vibration resistance in a 90-degree orthogonal configuration.
This series has achieved global industry benchmark status as original equipment door operators for leading elevator systems (such as OTIS 24V door drive units FAA24350DJ1, FAA24350DJ2, and M120R/L), transit turnstiles, smoke damper gates, and automated security barriers.
The precision-ground alloy steel worm screw meshes with a wear-resistant bronze or polymer worm gear housed inside a sealed lubricated enclosure.
