Optimising nature’s
electromagnetic forces The Cantoni Group is a global market leader in the design and manufacture of electric motors, brakes and specialised industrial tools. The company produces electric induction motors for use in pumps, fans, compressors,conveyors, etc., as well as electromagnetic brakes, electrohydraulic releases and others. Today it offers complete solutions with its latest innovative products keeping the company at the forefront of the electric-drive industry. Philip Yorke reports.
T
he history of Cantoni Group goes back to XIXth century. The Group comprises manufacturing plants located in Poland, with Cantoni Motor as the International Sales Office. Thanks to its constant and close cooperation with the various R&D departments of the Group, and in association with leading European universities, the company is able to create, produce and test specific solutions for a diverse range of industrial applications. These include electric motors for use in power plants, conveyers and mining equipment, as well as for the paper, marine, chemical and electromechanical industries. In addition Cantoni is involved in the design and manufacture of wide range of electrical apparatus, e.g. brakes, electrohydraulic releases, etc.
Advanced asynchronous power The global demand for complete solutions concerning electric motor drives, and in particular those involved in the production of motors equipped with electromagnetic brakes, continues to grow. One of the Cantoni Group’s state-of-the-art factories has for years been producing general purpose asynchronous motors with uprated output from 0.75kW to 250kW, and these are equipped with electromagnetic brakes for both AC and DC applications. The company’s broad spectrum of brake motors executions is very wide starting from a simple safety brakes for hoist applications, to powerful, silent drives for stage movement in theatres and out34 Industry Europe
door events. Heavy-duty brakes for use with conveyers in the mining industry and coal power plants are also produced by Cantoni with a high degree of protection from dust-intensive zones. Since 1954, the Cantoni Group’s brakes factory located in Poland, has continued to produce a wide range of electrical equipment, whilst optimising performance in order to meet the challenging demands of today’s competitive marketplace. The company’s AC and DC brakes are used to stop the rotation of a motor shaft or a machine after the voltage supply has been switched off. Cantoni’s HZg series three-phase AC brakes provide a braking torque of between 20 to 400Nm and are available in five different frame sizes. In addition, a broad range of DC brakes with a braking torque of up to 5000Nm in different executions and configurations in terms of supply and safety allows to use them in multi-purpose drives.
The safety-first NEX- series The Cantoni Group’s commitment to research and new product development has resulted in some major safety breakthroughs over the years. The company’s latest NEX-series electromagnetic brakes are designed to meet all the essential requirements for equipment and protective systems intended for use in potentially explosive atmospheres, such as gas and dust-laden atmospheres (zones 2 and 21), and this is underscored by its full ATEX safety certificate.
