R911258946
The R911258946 (MDD112C-N-020-N2M-130PA0), built by Bosch Rexroth Indramat is a Digital AC Servomotor showcasing high torque over a wide array of speeds. It stands out with its high cyclic load capacity which promotes continual start-and-stop usage, ensuring highly synchronous operation due to its combination of high feedback resolution and sinusoidal current. The motor requires a grounding connection with its drive amplifier and can operate without a blocking brake. Its flange can either possess threads or throughholes. However, it's vital to consider that the motor installation altitude does not exceed 5000m above sea level.
Regarding handling, the motor's housing can reach high temperatures during and post-operation, requiring a cool-down period before maintenance work. The motor should be kept dry and unloaded during storage and transportation. Notably, the motor should not be lifted utilizing the fitted blower as this may result in detachment. The R911258946 (MDD112C-N-020-N2M-130PA0) features protective plastic covers for the shaft and housing connectors, offering moisture protection. Essential details including continuous torque and current, torque constant, insulation class, etc., are recorded on its type plate. It also specifies a torque constant of 0.94Nm/A and winding resistance of 0.31 Ohms at 20°C. The motor also comes with a one-year backup support.
