Product catalog summary

Symbols and Specifications
This section lists symbols such as power (P), torque (M), speed (n), and others, specifying input/output shafts and directions. Compliance with ATEX 94/9/CE standards is noted for certain categories.

Modularity
Describes helical geared motor versions, including compact and motor coupling (PAM) versions, using materials like aluminum alloy and grey cast iron.

Design Features
Motovario products have specific surface finishes. Aluminum casings undergo deburring, shot blasting, and painting, while grey cast iron casings have an epoxy-polyester blue finish. Mechanical properties and resistance to heat and corrosion are tested.

Performance and Efficiency
Load capacity is verified by standards like DIN 3990 and ISO 6336. Dynamic efficiency is the ratio of output to input power, with average values for different gear stages.

Specifications
Motovario products use die-cast aluminum alloy cases with specific surface treatments. Grey cast-iron cases are painted with a blue epoxy-polyester coating, tested for adherence, hardness, and heat resistance.

Performance
Dynamic efficiency of H/HA-range gear reducers is calculated as output power over absorbed power, with average efficiencies for different stages. Load capacity is verified by standards.

Product Selection Guide
Selection involves input/output speeds and required torque, calculating input power, and consulting performance tables for suitable power. Includes combinations with 4-pole and 6-pole motors at 50Hz.

Thermal Power Specifications
Nominal thermal power values are given for specific conditions. Gear reducers with three stages do not require thermal verification.

Application Verification
For continuous operation over two hours, verify thermal limits using a formula involving correction factors for temperature, ventilation, and altitude.

Installation Recommendations
Guidelines include stable mounting, checking rotation direction, replacing seals after storage, protecting from weather, ensuring cooling, and gradually applying load. Contact technical service for extreme temperatures or speeds.

Correction Factors
Tables provide correction factors for ambient temperature, ventilation, and altitude, adjusting thermal power calculations.

Installation Guidelines

Ensure stable mounting to avoid vibrations.
Verify rotation direction before installation.
Replace seals after long storage.
Protect from weather and ensure cooling.
Contact service for extreme conditions.
Use proper mounting methods to avoid damage.
Lubricate surfaces to prevent issues.
Avoid painting rubber parts.
Replace shipping plugs with breather plugs.
Check lubricant levels.
Start operation gradually.
Protect parts from oil spillage.

Motor Mounting with PAM Flange B5

Ensure tolerances meet standards.
Clean surfaces thoroughly.
Fit coupling without excessive force.
Align correctly during assembly.
Use appropriate methods to avoid damage.

Radial Load Specifications

Admissible radial load values are in tables.
Maximum axial loads are 1/5 of radial load when combined.
Do not exceed maximum values.
Contact service for exceeding conditions.
Calculate radial load using specified formula.

Specifications
Conditions for exceeding radial load limits are outlined, advising contact with Technical Service for specific details.

Procedures
Radial load is calculated using a formula involving torque and diameter, with adjustments for non-central applications.

Standards
Maximum axial loads are 1/5 of radial load value when combined. Exceeding limits requires consultation.

Recommendations
Contact service for temperatures outside specified range. Special seals are needed for extreme temperatures.

Key Data from Tables
Tables provide maximum radial loads and moments of inertia, with adjustments for non-centered loads.

Lubrication
Oil changes are recommended after 10,000 hours or 2 years. Permanent lubrication is assumed for units without oil plugs.

Specifications and Requirements
Motors must operate below 0°C, with sufficient power for starting torques. Be cautious of impact loads on cast iron below -15°C.

Lubrication Guidelines
Oil changes are recommended based on service type and environment. Special seals are needed for extreme temperatures.

Lubricant Specifications
Recommended lubricants are specified for different temperatures and applications.

Installation and Maintenance
Specify mounting position for gear reducers. Some units require no maintenance, while others need oil plugs.

Oil Quantity
Oil quantities are indicative; verify and adjust as needed.
