MDC 3.30 B/SSA-0/S037

Product Description

The MDC 3.30 B/SSA-0/S037 is a premium servomotor made in Germany by the leading industrial automation company Bosch Rexroth Indramat. With a permanent magnet on its rotor, the MDC 3.30 B/SSA-0/S037 can achieve higher efficiency with little to no mechanical losses associated with the commutation. For AC machines like motors and generators, the rotor is the moving component, while the stator is the stationary component. In motors, the rotor generates the rotation by matching the moving magnetic field in the stator. For generators, the rotor is moved by the prime mover or energy source and induces the alternating current on the stator.

Servomotors like the MDC 3.30 B/SSA-0/S037 are generally preferred for highly precise applications because they provide a mechanism for detecting the rotor position or speed during operation. Usually, servomotors come with a tacho generator, which provides information about the rotor parameters. For this servomotor, the tacho EMK constant is 0.317 Vs/rad. During rated conditions, the shaft can run at a maximum speed of 1000 rpm. The effective current during rated conditions is 33 A. At most, however, the MDC 3.30 B/SSA-0/S037 can withstand a maximum of 300 amperes for a brief period of time.

The MDC 3.30 B/SSA-0/S037 has an insulation class of F and employs natural convection for cooling. With its sturdy motor housing, the machine has a protection rating of IP 65. Based on its nameplate, this motor has a torque constant of 0.8 Nm/A. The torque constant represents how much the machine’s output torque will change for every ampere of change in the input current. For this motor, specifically, changing the input current by one ampere will affect the output current by 0.8 Nm.
