Product Description
The MAC093C-0-KS-4-C/110-A-0/WI531LX from Rexroth Indramat is an AC servo motor designed to be controlled using compatible TDM, KDS, and DSC drive controllers. A TDM controller, also known as the Transistor Drive Module, relies on transistors, typically IGBTS and MOSFETS, to control and regulate the power supplied to the motors. The KDS controllers are meant for controlling AC motors as digital servos, allowing them to be controlled precisely for applications such as robotics. Lastly, the DSC controller is used for applications that require complex digital signal manipulation to control a motor.
The particular MAC093 model has a length C with a frame size of 093. The motor has a low-rated speed of 2000 rotations per minute, which makes it great for applications that require slow and precise movement of the shaft. To accurately move the shaft to the desired position, the MAC093C-0-KS-4-C/110-A-0/WI531LX features an incremental encoder with 2048 increments, which makes the step size resolution more precise. This encoder has a voltage rating of 5 Volts DC and outputs a square wave signal for every increment it has passed.
This motor requires approximately 240 to 480 Volts AC to operate and has a standstill current rating of 22 Amperes while outputting a standstill torque of 19.5 Amperes, providing approximately 0.9 Nm force per ampere of current, making this servo motor efficient for its design. The windings have a resistance of 0.433 ohms, which may further increase over time due to heavy load and may cause overheating. To combat heating, the MAC093C-0-KS-4-C/110-A-0/WI531LX relies on Natural convection and does not feature any extra cooling functions. It has a Thermal time constant of 50 minutes.
