MST290B-0018-FT-N0SN-NNNN

The Bosch Rexroth Indramat MST290B-0018-FT-N0SN-NNNN from the MST Synchronous Torque Motors series delivers a concise blend of power and precision with a nominal torque of 220 Nm and a power rating of 4.1 kW. This motor accommodates a voltage range of 179 - 475 V AC and operates at an input voltage frequency of 50 - 60 Hz across its 30 pole pairs, supporting precise control in demanding applications. Drawing a nominal current of 14.8 A and peaking at 60 A, the unit achieves a maximum torque of 700 Nm at a maximum speed of 350 rpm. The design boasts an efficiency ratio of 14.7 Nm/A, delivering consistent torque per amp for predictable performance.

The MST290B unit features a liquid cooling jacket integrated around the stator, ensuring optimal thermal regulation during continuous and peak loads. It employs a Winding type 0018 configuration within a frame length B housing, balancing size and output torque density for dynamic responsiveness. Though the motor lacks a formal IP rating, its robust, corrosion-protected enclosure resists environmental wear and supports installation in protected industrial zones. The absence of an IP classification underscores the need for dedicated mounts in clean, shielded cabinets to safeguard internal components.

Engineers benefit from straightforward integration thanks to standard mounting dimensions and compatibility with Rexroth’s drive controllers, enabling rapid commissioning and parameter loading. With substantial torque reserves and reliable thermal management, the MST290B-0018-FT-N0SN-NNNN excels in applications such as direct-drive rotary platforms, precision indexing tables, and high-torque inertia compensation. Its combination of high torque, liquid cooling, and precise pole-pair configuration makes it an ideal choice for advanced automation systems requiring durable, high-performance torque motors.
