Geared motors Bauer
Bauer Gear Motor is a world leader in innovative and energy-efficient gearmotor solutions. Founded in 1927, Bauer Gear Motor has grown worldwide to become a trusted source for high-quality, highly reliable gearmotors. Bauer engineers develop technically advanced solutions that feature energy-efficient motors combined with optimized gearboxes to offer customers the lowest possible cost of ownership.

Technical specifications:

• Motor power (P): 0.03 kW — 45 kW (varies by model/series; some ranges may exceed 45 kW).
• Nominal torque (Tn): from a few Nm to ~18,000 Nm+ for large units (depending on ratio and construction).
• Input / output speed: typical motor speeds 750–3000 rpm; output speed 0.2 rpm — 450 rpm (depending on the ratio).
• Transmission ratio (i): typical 3:1 → 10000:1 (in multi-stage / worm + helical combinations).
• Efficiency: 60% (worm) – >95% (multi-stage helical), depending on type and ratio.
• Backlash (gear play): typical 1–20 arc-min for helical/precision; versions with reduced backlash (precision) are available.
• Housing material: cast iron, aluminum, in some versions stainless steel (for aseptic/food).
• IP protection: standard IP55/IP65; options IP66/IP67/IP68 for wet/submersible environments.
• Motor insulation class: B, F, H (depending on the motor)
• Thermal protection degree: PTC thermistor/thermal switch, optional overheating protection.
• Lubrication: Periodic oil refill/change; some models with grease packed for life for reduced maintenance.
• Bearings: Long-life radial/thrust bearings; may include additional bearings on bare shafts.
• Operating temperature: typical -20°C … +40/50°C (extended temperature variants available).
• Vibration/shock class: Industrially designed, tested to relevant standards (e.g. ISO).
• MTBF/service factor: Designed for continuous operation (S1) in industrial conditions; typical service factor 1.0–1.5 depending on model.
• Connections/I/O: For modern motor variants — electric brake, encoder/resolver, temperature sensors, IP65 terminals.

Bauer Aseptic Drive

Typical applications:

• Industrial conveyors (conveyor belts, overhead monorails)
  Food / pharmaceutical applications (where hygiene and protection against infiltration are critical)
  Sewage treatment plants, pumps, agitators, water treatment plants, wet environments
  Heavy machinery, mixers, equipment where high torque at low speeds is required
  Installations in aggressive environments (chemical / wet / submersible)

Advantages:

• Reliability & durability — designed for intensive use.
  Variety of mountings & ratios — easily integrates into many applications.
  Special options — high IP, aseptic/ATEX variants, submersible.
  Advantageous total cost of ownership — high energy efficiency in helical, predictable maintenance.
