Packaging
Key Features for Usage:
  • Can be used as a generator (requires AFE function controller)
  • Rotor protected against corrosion and high-temperature demagnetization
  • Demagnetization index within 2%
  • Forced air cooling prevents overheating during continuous S1 duty
Frequently Asked Questions
Q: What is the maximum speed of this motor? A: The SRPM112H4F7-5C motor can reach a working speed of up to 24,000 rpm.
Q: Does this motor require a specific controller? A: Yes, it requires a VFD/VSD (Vector Control) because it cannot be started directly from a 3-phase AC supply due to rotor inertia.
Q: What is the efficiency rating? A: This permanent magnet motor has a high efficiency rating of approximately 95% to 95.5%.
Q: Can it be used in harsh environments? A: Yes, it features an IP54 protection rating, making it dust and water-resistant for industrial settings.
Q: How is the motor cooled? A: It uses a forced air cooling method to maintain optimal operating temperatures during continuous use.
Q: Can this motor function as a generator? A: Yes, it can be used as a generator when paired with a suitable motor controller that supports the AFE (Active Front End) function.
