The R911275109 (MHD071B-061-NG1-UN) is a reliable and maintenance-free synchronous motor from the MHD series by Rexroth Indramat. Teamed with digital drive controllers, it establishes a cost-effective automation system, ideal for machinery including packaging and food processing machines. Enhanced by electrical commutation, the motor guarantees continuous start-stop operation with high repetition frequencies. Its core components include a shaft, stator with winding, motor encoder, bearing, flange socket, shaft sealing ring, rotor with permanent magnets and a holding brake. The motor, protected by a prime black coating and IP 65 protection, is cooled by natural convection. It has a maximum speed of 6000 rpm, a time constant of 45 min, a theoretical maximum torque of 32.0Nm, and a moment inertia of 8.7 x 10-4. It is rated for an operating temperature of 0 to 40 degrees, and can have a maximum installation height of 1000 meters above sea level.
