Product Description:
The NAM1.3-08 belongs to the NAM Power Line Form Modules series produced by Bosch Rexroth Indramat. As a power-conditioning component, this module shapes and stabilizes the DC bus that supplies adjacent servo drives and inverters on an automation line. By housing commutation and smoothing chokes together with bus capacitors, it reduces ripple, limits inrush currents, and maintains consistent DC levels so that motion controllers can deliver repeatable torque and speed profiles. This arrangement helps keep the shared supply section stable during changing load conditions and repeated acceleration cycles.
The bus connector carries 16 signal and power conductors, giving the module a direct interface to neighboring drive sections. Internal energy storage is provided by a bus capacitor rated at 1 mF and intended for continuous operation at 700 V. A commutation choke supports up to 15 A of line current, and its inductance of 0.38 mH slows current rise time to protect semiconductor switches from high di/dt events. For safe installation, at least 80 mm of free clearance is required above and below the heat-dissipating surfaces, while the DC bus lead must not exceed 1 m so loop inductance stays low. Connection conductors use 2.5 mm² for link leads, 4 mm² for mains leads, and 10 mm² at the power terminal clamp for temperature-stable wiring.
The choke core generates losses of 28 W during continuous operation, so placement must accommodate this thermal load. Downstream smoothing hardware handles a maximum of 25 A; its copper and core design dissipate about 50 W and add only 3.5 kg to the assembly, which helps keep cabinet loading moderate. Up to 70 mF of additional capacitance can be connected in parallel when long cable runs require extra energy buffering, provided the link remains under the stated 1 m length. The stated losses and current capacity should be considered when sizing enclosure airflow, protective devices, and connecting conductors.
