Electric Motor Specifications
Specifications for HB and HBZ motors include IEC standardization, asynchronous three-phase design, and IP 55 protection, suitable for inverter duty.
Frequency and Power Considerations
Motors wound for 50 Hz can operate at 60 Hz with a 20% speed increase, with recommendations for winding motors from size 160 upwards for 60 Hz.
Duty Cycles
Guidelines for short time duty (S2) and intermittent periodic duty (S3) are provided, including a formula for calculating the cyclic duration factor.
Standards and Norms
The document references CENELEC and IEC standards for nominal powers, dimensions, protection, mounting positions, and cooling.
Motor Types and Applications
Various motor types are described, including asynchronous three-phase motors and brake motors, suitable for different applications with low noise and dynamic characteristics.
Economic and Dimensional Features
Motors are highlighted for maximum economy, reduced dimensions, and moderate braking torque, suitable for safety stops and light movements.
Specifications

Efficiency and Standards
Motors achieve high efficiency, complying with energy-saving regulations, available in efficiency class IE3 for HB and HE.
Design and Construction
The electric design includes a terminal block and nameplate, with precise mechanical construction and options for non-standard designs.
Symbols and Units
A comprehensive list of symbols and units used in the catalog and formulae is provided.
Mounting and Lubrication
Specific mounting positions and lubrication requirements are outlined, with synthetic oil suitable for temperatures up to 110°C.
Designation and Selection
Designation codes for gearmotors are outlined, including mounting positions and motor specifications.
Additional Information
Sections on service factors, radial loads, selection tables, and structural details provide a comprehensive guide for motor selection.
Seal Rings
The lifespan of seal rings ranges from 3,150 to 12,500 hours, influenced by sliding speed, temperature, and environmental conditions.
Oil Quantities
A table lists required oil quantities for different gearmotor sizes, from 0.1 liters for size 118 to 0.95 liters for size 742.
Plug Position
Gearmotors have one plug (two for size 742) positioned as shown, with no level plug provided.
Thermal Power (Pt)
Nominal thermal power (PtN) is applicable at the gear reducer's input side under continuous duty at a maximum ambient temperature of 40°C.
Thermal Power Verification
Verification is generally not required unless specified, necessary if ambient temperature exceeds 30°C or running at full power.
Service Factor (fs)
The service factor accounts for operating conditions, crucial for gearmotor selection and verification.
Selection Process
To determine the appropriate gearmotor size, consider required output power, angular speed, and operating conditions.
Verification
Radial load and starting frequency should be verified according to specified instructions.
Motor Power Considerations
Motor power should match the power required by the driven machine, considering efficiency and other transmissions.
Driving Machines with High Kinetic Energy
For machines with high inertia or speed, avoid using irreversible gearmotors to prevent overloads.
Operation at 60 Hz Supply
When supplied with 60 Hz, gearmotor specifications change: speed increases by 20%, power may remain constant or increase.
Determining Gearmotor Size
Gather necessary data such as required output power, speed, and running conditions to calculate the service factor.
Verifications
Verify radial load limits, starting frequency, and ensure maximum torque peaks do not exceed specified limits.
Considerations on Selection
Motor power should closely match the power rating required by the driven machine.
Radial Loads on Shaft Ends
Radial loads must not exceed specified limits, with permissible loads provided in tables.
Specifications
Motors (category TX) do not meet IE3 efficiency class as per IEC 60034-30 standards, with nominal power specified for intermittent duty S3 70%.
Procedures
Thermal power verification is necessary for continuous duty with ambient temperatures over 30°C.
Standards and Recommendations
Guidelines for motor mounting positions and dimensions are provided, with efficiency considerations for gear reducers.
Key Data from Tables
Selection tables provide specifications for various motor sizes and configurations, including power and torque.
Critical Information
Efficiency values are crucial for determining the suitability of gear reducers, with safety devices recommended to prevent exceeding maximum torque.
Specifications and Efficiency
Worm gearmotors have lower static efficiency at startup due to friction, with efficiency increasing as speed increases.
Irreversibility
Worm gearmotors are dynamically irreversible when efficiency is below 0.5, crucial for load holding without brakes.
Overloads
Worm gear pairs can handle high overloads, but must remain below maximum allowable torque.
Starting Torque
Verify maximum torque sufficiency using a specific formula considering starting friction and efficiency.
Braking and Stopping
For high kinetic energy machines, a statically reversible gear reducer is recommended.
Operation with Brake Motor
Formulas for calculating starting and braking times are provided, noting stabilization after warm-up.
Friction Surface Duration
A formula estimates permissible applications between air-gap adjustments.
Structural and Operational Details
Details on fixing bolt dimensions and maximum allowable bending moments are provided.
Accessories and Non-standard Designs
Information on low-speed shafts and flanges is included, with recommendations for using locking adhesives.
Specifications and Components
Specifications for gear reducers and components such as flanges and torque arms are provided, emphasizing correct fitting and alignment.
Ordering and Designation
When ordering components separately, include catalog and gear reducer size data.
Installation and Maintenance
Stable and vibration-free mounting surfaces are crucial, with proper air circulation for cooling.
Fitting Components to Shaft Ends
Recommendations for machining tolerances and lubricants to prevent seizure and corrosion are provided.
Shaft End of Driven Machine
Tolerances for the shaft end of machines are specified for proper fitting with the gear reducer.
Motor Replacement
Guidelines for replacing motors emphasize standard mating surfaces and proper lubrication.
