SD-B4.070.030-05.000
The Bosch Rexroth Indramat SD-B4.070.030-05.000 is a permanent-field servomotor equipped with Class F insulation as per DIN VDE 0530 standards. It supports IM B5 and IM V3 mounting and performs electronic commutation. Pairing with a TA or TC series inverter with a 10/20 A peak current is mandatory. Featuring a 142 mm flange, it manages axial and radial forces and maintains a fixed bearing on the driving side to prevent thermal expansion. Variable maximum axial force limits are dependent on mounting. The motor lacks an in-built encoder but includes a tacho for velocity feedback and a significant overload capacity. Plastic connectors manage power and feedback; high surface temperatures necessitate cooling before contact. Avoid shaft impacts to protect the rotor and ball bearings. It delivers a torque constant of 0.93 Nm/A, requires the flange to remain fluid-free when vertically mounted, and should remain structurally unaltered aside from tacho board replacement.
