Refrigeration compressor motors
Asynchronous Roto-Stators
These motors, Sisme's core product, equip hermetic and semi-hermetic compressors from the industry's leading manufacturers. They are developed in cooperation with our customers according to the increasingly stringent requirements of the sector.
Features
- RS asynchronous for hermetic or semi-hermetic compressors
- Compression types: scroll, reciprocating, screw
- High energy efficiency, reliability and minimal maintenance.
Technical data
- 2/4 poles on different sizes and dimensions
- Power output from 2.5 HP to 50 HP
- Torques up to 470Nm
- Standard and customisable voltage ranges
- Frequencies 50 and 60 Hz
- Three-phase and single-phase
Applications
- Industrial and domestic refrigeration
- Air conditioning
- Power Generation
LSPM and IPM Synchronous Rotors
As an alternative to asynchronous versions, they are used for different types of compressors, scroll, reciprocating, and screw, allowing them to maximise electrical efficiency and reduce energy losses during the gas compression process.
Features
-
LSPM - Line Start Permanent Magnet
- are self-starting RS with direct mains supply
- Asynchronous start-up without inverter
- Synchronous operation at constant speed
- High electrical efficiency, ease and economy of installation -
IPM - Internal Permanent Magnet
- They are inverter-powered brushless RS
- Variable-speed Synchronous operation
- Very High electrical efficiency thanks to High-potential permanent magnets - Reliability, robust construction and minimal maintenance.
Technical data
- 2/4 poles on different sizes and dimensions
- Power output from 2.5 HP to 50 HP
- Torques up to 320Nm
- Standard and customisable voltage ranges
- Variable speed (if inverter-powered)
Applications
- Industrial and domestic refrigeration;
- Conditioning;
- Power generation;
