Motor spindles

Maximum performance in machine tools

Motor spindles

Siemens offers the perfect portfolio of motor spindles that deliver maximum productivity and precision and ensure optimum performance and product quality. Mechanically built-in-motor solutions are extremely compact and achieve maximum rigidity, a requirement for achieving maximum speeds and exact concentricity.

Looking for motor spindles for use on milling machines and machining centers? Your first choice should be Siemens’ compact water-cooled 2SP1 motor spindles. In contrast with externally driven motor spindles, we offer a high degree of compactness, precision and productivity. Our compact "all inclusive" spindle solution will provide you with additional benefits, too. For example, the built-in motor means fewer parts compared to a belt drive solution. And the sensor technology for indexing and monitoring is built in. In short, the 2SP1 is the economical standard for your motor spindle requirements.
