Brief: Let’s dive in — see this solution in action and notice the key moments. This video provides a comprehensive walkthrough of the care and maintenance procedures for permanent magnet motors. You'll learn practical maintenance techniques, discover how to maximize bearing life through proper lubrication, and understand the thermal protection systems that ensure long-term reliability in industrial applications.
Related Product Features:
  • Achieves up to 30% energy savings compared to traditional induction motors with high efficiency across 20-110% load range.
  • Delivers constant torque across wide speed ranges without forced ventilation, suitable for variable speed applications.
  • Features bearings with L10 life expectancy of 100,000 hours and easy re-lubrication via grease nipples for reduced maintenance.
  • Utilizes high-performance NdFeB rare-earth magnets with epoxy coating for superior magnetic performance and corrosion resistance.
  • Incorporates PTC thermistors for thermal protection against overheating from phase loss, overload, and voltage irregularities.
  • Operates synchronously with stable speed unaffected by voltage or load changes, eliminating slip and rotor power losses.
  • Maintains high power factor throughout speed range, reducing stator current by 15-30% and lowering transmission losses.
  • Experiences 15-20°C lower temperature rise than comparable asynchronous motors due to high efficiency and low loss design.
Faqs:
  • What maintenance is required for permanent magnet motors?
    These motors require minimal maintenance due to long bearing life (up to 100,000 hours) and feature grease nipples for easy re-lubrication, significantly reducing maintenance frequency and downtime.
  • How do permanent magnet motors achieve energy savings?
    They achieve 10-40% energy savings through high efficiency across broad load ranges, constant torque delivery without forced ventilation, and reduced stator current by 15-30% due to high power factor operation.
  • What protection features are included in these motors?
    The motors feature integrated PTC thermistors that provide thermal protection against overheating from phase loss, overload conditions, and voltage irregularities, ensuring operational safety.
  • Can these motors be customized for specific applications?
    Yes, Greef offers comprehensive customization with speed ranges from 0-8000 RPM, premium SKF bearings, and tailored solutions for electric vehicles, robotics, and industrial automation.
