IndraDyn S series synchronous servo motors developed by Bosch Rexroth can continue to be upgraded in output power, performance and accuracy. Each motor pole is mounted separately before the stator assembly to prevent the motor from spinning and maximize the copper content. It is said that such a design can make the maximum output power of the motor in the smallest size. At the same time, many specifications of the series of products, torque range from O. 1 to 240Nm.
