M Squirrel Cage

The Master Line (M Line) motors stand out for the flexibility of their electrical and mechanical design.
They are versatile motors that allow different configurations and can be applied in harsh environments that demand high resistance and durability, making them suitable for a variety of applications. They make it easy to implement modifications to their designs, in order to make them interchangeable with existing motors, reducing operating costs resulting from downtime to change motors.
They can also be designed for frequency inverter drive, which enables precise speed control as well as high torques during start-up.

Applications:
The Master Line stands out for its concept of versatility, providing adaptable motors capable of offering reliable and dedicated solutions in various segments, such as Oil & Gas, Mining, Cement, Energy, Water & Wastewater, Pulp & Paper, Steel, Marine and Sugar & Ethanol.

Flexibility

Flexibility for interchangeability (plug & play)
Customized or tailormade in their design of electrical and mechanical to meet with the existing motors, cutting down operating cost with downtime for motor replacement project.

Performance

High Performance
With the use of modern software that guarantees precision in the design, maximum performance can be achieved with these motors.

Design

Reliability and Robustness
Versatile motors with different configurations suitable for several environments which demand high resistance and durability, adapting to different applications.

Cost

Simple and Low Maintenance
Motors can be supplied with the cooling system which vary according to the type of the driven machine, application and environment where they will be installed.

Optimized

Optimized Design
Use of high-quality manufacturing materials, such as a stator made of silicon steel plates with low specific losses, combined with high quality manufacturing and design optimizations, allow this product line to deliver reduced losses, and consequently high efficiency.
