MAD IndraDyn A Motors

Bosch Rexroth IndraDyn A MAD Motors are housed asynchronous servo motors designed for air-cooled servo and main-spindle applications. The MAD series is used in demanding equipment such as machine tools, printing presses, and metal-forming systems where high output and reliable speed control are required. These motors combine strong power density with ratings that reach up to 93 kW and maximum speeds up to 11,000 rpm, depending on the configuration. Feedback options include integrated high-resolution encoder systems, with single-turn and multi-turn versions available for accurate and repeatable drive control. Mechanical configurations include smooth or keyed shafts, optional holding brakes, and bearing versions suited for standard operation, higher radial-load demands, or high-speed use. Mounting options include flange mounting as well as flange-and-foot installation. The series provides IP65 protection, including the fan motor, and uses blower-based surface ventilation with a removable fan unit for easier maintenance. Proper ventilation is required during operation, as the motor is not designed to run without active cooling.
