2AD134D-B35LR1-CS37-B2N1
The 2AD134D-B35LR1-CS37-B2N1 is an AC induction motor manufactured by Bosch Rexroth Indramat within the 2AD 3-Phase Induction Motors series. In automated lines it converts electrical energy into continuous torque for pumps, spindles, or material-handling axes while remaining compatible with closed-loop drive controllers.
The frame is identified by Motor size 134 and the active core depth by Motor length D, a combination that defines the continuous power envelope. Heat generated in the stator is removed by an integral Axial Blower, allowing full-load operation without external cooling ducts. For stop-and-hold duties the electrically released brake supplies 100 Nm of static torque, and standard bearings support radial loads typical of belt or gear transmissions. Installation flexibility comes from flange and foot mounting; the housing can be bolted to a base plate or a machine wall without additional brackets. The rotor is balanced with the full key but runs without a shaft seal to minimise friction, and the rear side is supplied without a second shaft end to shorten the overall length. Dynamic behaviour meets vibration grade R, so resonance transfer to attached mechanisms is limited during speed ramps.
Electrical interfacing is straightforward: the three-phase power lead exits to the right of the fan cowling, yet the plug face sits on the left when the shaft is viewed from the front, simplifying cable routes in compact cabinets. The motor draws supply through a sealed Power Plug that also carries blower voltage, reducing wiring points. Position and speed feedback are provided by a digital servo feedback unit with a multiturn absolute encoder, enabling the drive to regain position immediately after power restoration. A CS winding pattern, standard-duty bearings, and the absence of a shaft seal complete a configuration aimed at reliable service in high-cycle industrial machinery.
