Product Description
The 2AD104D-B35OB1-FS26-B2N1 by Rexroth is a special AC servo motor that incorporates an electrically released blocking brake. For most of Rexroth’s motor series, the blocking brake may either be of the standard type or of the heavy-duty type. Standard blocking brakes typically have lower braking torque and cannot withstand the motor’s rated torque. For 2AD104 motors, the electrically released blocking brake works whenever it receives a braking signal. When the motor is running, the brake is disengaged to allow the rotor to run freely. After receiving the braking signal, the brake actuator releases the brake to hold the rotor in place. For this motor model, the blocking brake requires a 24 V supply and 60 VA.
To maximize the capabilities of the 2AD104D-B35OB1-FS26-B2N1's blocking brake, careful consideration of both the release and locking delays is a must. Based on Rexroth Bosch’s standard datasheet for 2AD104 motors, the brake’s release delay is 100 milliseconds, while the locking delay is 60 milliseconds. The release delay is slightly longer than the locking delay because the controller implements an intentional delay to verify if the braking signal is not a noise. During braking operation, the brake draws a total of 1.1 amperes.
Aside from its powerful blocking brake, the 2AD104D-B35OB1-FS26-B2N1 also features a digital servo feedback, a set of flange or foot screws, a B-shaft type, a standard mechanical bearing, and an FS winding. Complementary to these features, the 2AD104D-B35OB1-FS26-B2N1 has an impressive set of nameplate ratings. Based on its nameplate and datasheet, the 2AD104D-B35OB1-FS26-B2N1 runs at a rated/nominal speed of 1800 rev/min at a power and torque rating of 12.1 kW and 64 Nm, respectively.
