Low Voltage High Efficiency Motors

Product catalog summary

General Characteristics: The SEE series of three-phase low voltage high efficiency motors, manufactured by Cantoni Group, range from 0.55kW to 315kW with mechanical sizes from 80 to 355mm. The series includes higher power motors (Sh series) with mechanical sizes 355, 400, 450, and 500. These motors are designed for continuous duty (S1) and operate at 400/690V, 50Hz. They feature class F insulation, an ambient temperature range of -20°C to +40°C, and are suitable for altitudes up to 1000m. The motors have an IP55 protection rating and are cooled using the IC411 method.

Construction and Features: The motors are available in various construction types (IM1001, IM2001, IM3011) and can be started directly on line or with a frequency inverter. They have anti-friction bearings, a noise level compliant with EN 60034-9, and a vibration severity grade N. Thermal winding protection is provided by PTCs, and additional features like space heaters and insulated bearing chambers are available on request. The motors are painted blue (RAL 5010) and have a cast-iron frame.

Application and Operational Conditions: These motors are suitable for general industrial use, driving machines and devices in continuous duty without frequent starting and reversing. They can operate in dusty environments but should be protected from chemically aggressive contaminants and explosive mixtures. For outdoor use, protection against weather elements is recommended. When powered by frequency inverters, speed control is possible within specified ranges.

Technical Data: The catalogue provides detailed technical specifications for various motor types, including rated power, speed, current, power factor, efficiency, starting current, torque, rotor inertia, mass, and sound pressure level. The data is organized by motor type and pole number, covering speeds from 500 to 3000 rpm.

Dimensional Drawings: The document includes dimensional drawings for horizontal, foot-flange, and vertical executions of the motors, detailing measurements for various components and configurations.
