About Motovario
Industrial Gearmotors & Precision Speed ReducersTECO Group
Motovario, founded in 1965 and headquartered in Formigine, Italy (Modena region), is an established manufacturer of gearmotors, speed reducers, and power transmission systems for heavy industrial equipment, now owned by the TECO Group since 2015. Motovario's engineering approach emphasizes modular design: a single motor and gearbox family accommodates 10+ power ratings (0.37–400 kW) and reduction ratios through interchangeable reducer cartridges, enabling customers to right-size equipment without full redesign. The company supplies helical, bevel-helical, worm, and planetary gear families with proven track records in 20+ years of continuous operation in food processing, chemical processing, mining, and packaging automation.
Motovario's helical gear reducer lineup (H series) offers high efficiency (92–96% per stage, up to 98.5% dual-stage) with quiet, compact designs ideal for conveyor drives, mixers, and precision indexing in automation. The bevel-helical PBZ series is engineered for applications requiring mixed-axis drive (input/output not parallel): mining hoists, marine propulsion gearboxes, and industrial crane slewing drives benefit from the PBZ's robust construction (up to 4 reduction stages) and high shock-load tolerance. Worm reducers (NMRV, NMRV-P series) feature warm-oil bath lubrication and self-locking ratios (no backdrive without external load), making them essential for vertical-lift applications (shop hoists, bucket elevators) and security-critical systems where motor failure must not drop load.
All Motovario motors comply with IEC 60034 (electric motor standards) and are available in premium IE3 efficiency class—a European regulatory minimum since January 2017 for motors >0.12 kW. IE3 motors reduce energy consumption 15–20% vs. older IE2 designs; over a 20-year lifespan, energy savings justify higher capital cost. Motovario also produces low-voltage design (LVED) IE3 motors rated 0.37–400 kW, enabling integration into complete motor-reducer packages with single electrical specification and one power cord.
Core industries served include food processing (small sanitary pumps, dough-mixer drives, conveyor sorting systems—all stainless-steel or coated for hygiene), chemical manufacturing (thick-oil transfer pumps, crystallizer agitators, chlor-alkali cell drives), aggregate and mining (vertical-shaft bucket elevators, screen vibrators, conveyors handling 50–100-ton/hour loads), and beverage bottling (line-shaft drives, capping-machine indexers, label-application gearboxes). Motovario's partnerships with distributors in 80+ countries and OEM integration into major equipment brands (Tetra Pak filling machines, Sennebogen material handlers) position the brand as a mission-critical, field-proven component.

Frequently asked questions
What's the difference between worm (NMRV) and helical reducers in Motovario's line?
Worm reducers offer high reduction ratios (1:20 to 1:100) in compact space with self-locking (load cannot backdrive motor), ideal for vertical hoists and security-critical systems; they require warm-oil lubrication and have lower efficiency (60–75%) due to sliding friction. Helical reducers have lower ratios (1:3 to 1:20 depending on stages) with higher efficiency (92–98%), suitable for high-throughput horizontal conveyors and mixers where energy cost is critical. Choose worm for vertical lift and load-holding; choose helical for high-volume production and efficiency.
What does IE3 efficiency mean, and is it required for Motovario motors?
IE3 (Efficiency Class 3) per IEC 60034-30 means the motor converts 88–92% of electrical input to mechanical output (vs. older IE2 at 80–85%), reducing waste heat and electricity cost. Mandatory in Europe for motors >0.12 kW since January 2017; North America has no federal efficiency mandate but energy rebates often incentivize IE3 selection. Motovario produces IE3-compliant LVED motors paired with reducers; legacy IE2 motors are still available for replacement applications but are being phased out.
Can a Motovario worm reducer self-lock if I lose electrical power?
Yes—the worm's helical geometry inherently prevents backdrive when the motor de-energizes because the high friction angle (25–45°) exceeds the load's torque angle. A 1:40 worm reducer will hold a hanging load indefinitely without motor power, critical for safety hoists. However, continuous overload (exceeding design torque + safety factor) can overcome self-locking through heat-induced friction loss; verify load margin and run periodic load tests on life-critical vertical systems.
What lubrication type does Motovario use, and what's the maintenance interval?
Helical reducers use ISO VG 220–320 mineral oil or synthetic (PAO/ester) lubricants. Drain-and-refill intervals are 2,500–5,000 operating hours (typically 1–2 years) depending on duty cycle and environmental contamination. Worm reducers require warmer-grade oils (ISO VG 320–460) to maintain viscosity during sliding-friction heating; change intervals are 1,000–2,000 hours because worm friction generates higher temperatures and accelerates oil oxidation. Always verify your machine's oil change records and use Motovario-approved lubricants to maintain warranty.
How do I match Motovario output torque to my conveyor or mixer drive requirement?
Calculate required output torque: Torque (Nm) = Power (kW) × 9,549 ÷ Speed (RPM). For example, a 2 kW motor at 1,450 RPM supplying a 1:10 helical reducer outputs 1,450÷10 = 145 RPM at (2 × 9,549 ÷ 145) ≈ 132 Nm. Multiply by a 1.3–1.5× service factor for shock loads (conveyor start-up, mill startup transients) to select the next-larger Motovario gearmotor size; undersizing risks premature reducer failure and motor overheating.
