Double-speed conical-rotor brake motor

A fresh addition to our product range of lifting motors is the recently developed double-speed conical-rotor brake motor to drive the main lift of 5t and 10t wire rope electric hoists. It’s been designed to meet the need for yet untapped, but increasingly reflected in the crane industry multi-speed alternatives to the common single-speed conical brake motors established on the Bulgarian market and abroad. The motor combines all the advantages of the integrated into the motor conical brake, that is, the possibility of frequent starts and stops, no separate excitation of the brake, simultaneous release of the brake and start of the motor, meaning a long service life, and a durable cast iron construction. What's more, the adoption of the iconic conical brake design, which creates its moment by friction in the fan housing of the electric motor rather than in the rear shield and thus contributing to a better heat dissipation, further increases the reliability of the brake and the motor overload capacity while simplifying the maintenance of the brake unit at the same time. It has the distinctive features of customer-specific joining and is available in various pole-changing ratios to suit the hoist lifting speeds and reeving arraignment.
