Linear motors
Bosch Rexroth offers the following linear motors:
ML3 linear motors. The self-cooled iron-core linear motors of the ML3 series offer high forces in the smallest installation space. Synchronous linear motors of the ML3 series are the high-output direct drive alternative to classic ball screw drives. With fewer wearing parts, higher mechanical rigidity and the highest positioning accuracy and dynamism, they contribute to a significant increase in productivity in factory automation. Thanks to the space-saving electromechanical design, these linear motors can also be installed in particularly limited installation spaces. With their high synchronous running quality, the motors achieve the highest quality in production due to their low detent forces and the resulting low force ripple. The design as a self-cooled motor series makes it possible to dispense with a coolant device on the machine and at the same time simplifies the motor installation.

MLF linear motors. Compact design, high degree of protection and enormous maximum forces – these are the characteristics with which MLF synchronous linear motors meet the challenges of machine tools. Together with the low force ripple, these motors are ideal for fast movement of large masses in rough environments. Due to the complete encapsulation with titanium-alloyed stainless steel sheet, the motors are suitable for use in the immediate machining area of machine tools. Practical sizes in standard encapsulations or thermal encapsulation for minimal heat input into the machine are available. The combination of several linear motors – whether in series or parallel – leads to completely new machine concepts with significantly increased machining forces.

MCL ironless linear motors position small masses extremely precisely and with high synchronism. The difference to the iron-core variant is the ironless structure of the primary component with the completely encapsulated three-phase copper winding. The U-shaped secondary component (MCS) contains the permanent magnets and encloses the primary component (MCP). Due to this design, neither attraction forces nor detent forces occur between the primary and secondary components and the force constant is linear. These aspects, in combination with the relatively small moving mass of the primary component, allow a very high dynamism with highest precision at the same time.
