The R911307307 (MSK101E-0450-NN-M1-BG2-NNNN) synchronous motor by Bosch is known for its longevity, efficiency, and affordability. Equipped with a 24VDC blocking brake, the motor produces blocking torque of 70 Nm, enabling it to maintain a stationary shaft. The 53 ms connection and 97 ms disconnection times ensure smooth operation. This motor utilizes ambient air for cooling, with an additional blower for further cooling during continuous usage. It houses 4 pole pairs that create 1.080 mH winding inductivity. With a natural cooling mode, it can deliver a consistent 70-80.5 Nm of torque from a 58.3-67.6 A current. The motor can generate up to 231 Nm of torque, using peak 262.4 A current at a top speed of 6000 rpm. The weight of this standard design motor is 57.3kg. The R911307307 (MSK101E-0450-NN-M1-BG2-NNNN) model is ideally operable in 0 to +40 degrees Celsius, perfect for various industrial applications.
