1MS160N-4A-A1/S010

The 1MS160N-4A-A1/S010, manufactured by Bosch Rexroth Indramat, is part of the 1MB High-Speed Asynchronous Motors lineup. It functions as an asynchronous spindle motor stator designed for high-performance spindles in machine tools and transfer lines. The stator converts the rotating magnetic field into electrical current with precision, enabling efficient energy conversion at high rotational speeds. Its compatibility with 1MB motors ensures seamless integration within complex motion control systems.

Key technical specifications include a Rated Speed of 3000 rpm and a Max Speed of 8000 rpm, coupled with a Rated Power output of 28 kW. Electrical requirements demand a Current Rating of 75 A with a Max Current of 170.8 A on a Bus Voltage of 540 V DC. Mechanical durability is reinforced by a Rated Torque of 89 Nm and a Max Torque of 223 Nm, while an IP Rating of IP00 designates its enclosure class. Thermal management relies on a Thermal Time Constant of 300 s and an Inductance of 1.251 mH, supporting continuous operation within an Ambient Temperature Range of 0…40 °C.

The stator’s Frame Size of 160 and an approximate Weight of 28.1 kg are optimized for 4-pole configurations with two pairs of poles, and integrated PTC and NTC resistors facilitate precise temperature monitoring. An aluminum cooling jacket complements the standard liquid cooling system, enhancing heat dissipation under high loads. Robust construction and precise winding codes ensure long-term reliability, making the 1MS160N-4A-A1/S010 ideal for demanding high-speed machining and global industrial applications.
