Product Description:

The MAF130B-0250-FQ-S2-HG0-05-A1 is a liquid-cooled asynchronous housing motor built by Bosch Rexroth Indramat within the MAF IndraDyn Asynchronous Motors series. The unit converts three-phase electrical power into controlled rotary motion for conveyors, spindles, and auxiliary axes in automated cells. Its design supports continuous duty while minimizing thermal drift, giving a compact motor option where an integral liquid circuit is preferred. This layout is suited to applications that need stable speed, reliable heat removal, and compact installation around the machine frame.

The motor reaches a rated speed of 2500 rpm, so the connected drive can support high-speed operation in continuous service. Heat is removed by liquid cooling that circulates behind the stator jacket, and a 1/4 inch thread on the B-side manifold provides the inlet for hose connection. Position feedback is delivered by a single-turn absolute encoder with 2048 increments over the EnDat2.1 digital interface. This feedback arrangement lets the drive read rotor position immediately after startup and maintain accurate speed control during load changes. Because the terminal box is turnable and mounted on the B-side, the power cable can be aligned with nearby ducting. Dynamic balance complies with vibration level A according to DIN EN 60034-14, and the flange mounting pattern supports axial alignment.

The rotor is supported by a fixed bearing on side A, and the plain shaft exits through a shaft sealing ring to maintain the IP65 enclosure rating. The shaft seal also helps limit the entry of dust and splash during routine operation. No holding brake is installed, so static torque must be supplied by the drive or by an external clamp. The windings use class F insulation, allowing the frame length B motor to handle the temperatures associated with heavy cycling. Operation is specified for ambient conditions from 0–40 °C, which matches typical industrial indoor environments.
