Geared Motor Series M

Product catalog summary
Overview: The document provides comprehensive technical specifications and descriptions of geared motors and transmission solutions, with a focus on the Series M Helical In-Line geared motors. It emphasizes the company's ability to create custom-engineered solutions for industries such as food, energy, mining, automotive, aerospace, and marine propulsion.
Product Range: Various series of geared motors are listed, including Series X Cone Ring, Series J Shaft Mounted Helical Speed Reducers, and Series C Right Angle Drive Helical Worm Geared Motors. Each series is tailored for specific applications, offering features like overload protection, high torque coupling, and diverse mounting options.
ATEX Compliance: The document confirms compliance with the ATEX Directive 94/9/EC, ensuring safe use in potentially explosive atmospheres. Certification for standard gearboxes and geared motors, including CE and Ex marks, is available.
Series M Specifications: Series M inline geared motors and reducers are noted for their efficiency and compact design, suitable for applications up to 90kW and 11,000 Nm. The range includes twelve sizes with various reduction ratios and mounting options, compatible with IEC and NEMA standard motors, and features like double oil seals and backstop modules.
Design Features: Key design features of the Series M include patented motor connections, compatibility with standard motors, and availability of brake geared motors. Continuous design improvements are noted, with potential changes in specifications.
Load Classification and Service Factors: The document explains ratings and service factors for gear unit selection, providing tables for mechanical service factors and load classifications by application. It stresses selecting units based on actual load conditions and service factors.
Selection Procedure for Motorized Units: A step-by-step procedure for selecting motorized units is outlined:
  • Determine Mechanical Service Factor (Fm): Calculate based on load classification and service duration.
  • Determine Required Output Torque: Use the formula: Absorbed power x 9550 / Gearbox output speed.
  • Select Geared Motor: Choose a motor size larger than the absorbed power.
  • Check Output Torque: Ensure the selected unit's output torque meets requirements.
  • Check Service Factor: Verify the adequacy of the service factor.
  • Check Overhung Loads: Compare calculated loads with allowable limits.
Unit Versions and Output Shaft Options: Various unit versions and output shaft options are detailed, specifying dimensions and configurations for different applications.
Motor Adapters: Information on motor adapters for different flange types and unit sizes ensures compatibility with various motor frames.
Critical Considerations: Consultation with application engineering is advised for conditions like high mass acceleration factors or ambient temperatures above 40°C.
Specifications: Specifications for motorized backstop modules are outlined, highlighting wear-free operation above lift-off speed and suitability for temperatures from -40°C to +50°C.
Procedures and Warnings: Ensure all machinery is secure before maintenance, as removing the motor or backstop releases the drive.
Technical Data: Detailed tables provide motor frame sizes, lift-off speeds, rated locking torques, and dimensions, along with calculations for overhung and axial loads.
Recommendations: To reduce overhung loads, increase sprocket or gear diameter. If limits are exceeded, consider alternative mounting or extending the gear unit shaft.
Tables and Calculations: Extensive tables detail input speeds, output speeds, exact ratios, output torques, input power, and overhung loads, essential for determining appropriate configurations and ensuring system operation within limits.

RATINGS & SERVICE FACTORS Gear unit selection is made by comparing actual loads with catalogue ratings. Catalogue ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalogue ratings. i.e. Equivalent Load = Actual Load x Service Factor Mechanical ratings and service factors Fm and Fs Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day continuous running under uniform load conditions. Catalogue ratings...
