MDD115B-N-015-R2L-130GA2
The MDD115B-N-015-R2L-130GA2 is a digital AC servo motor developed by Bosch Rexroth Indramat. It features a permanent magnet made from rare earth or iron oxide materials, contributing to its low inertia and ability to carry out continuous start-stop operations with high repetition rates. A key specification of this motor includes a nominal speed of 1,500 rpm, a winding inductance of 9.2mH, and a maximum torque of 118.2 Nm. It exhibits a temperature-dependent winding resistance of 0.39 Ohm and torque constant of 1.40 Nm/A at 20 degrees Celsius. The motor's housing is designed for cooling by natural convection and surface cooling. Further notable features include a standard centering diameter of 130mm, a 60 Nm blocking brake, and built-in temperature sensors for overheating protection. The motor's compact build, ability for multi-positional installation, and high power to weight ratio, all contribute to its operational efficiency. Moreover, it complies with the R balance class, in line with DIN VDE 0530, section 14 (2/93 edition).
