Product Description:
The MST110A-0230-NC-N0CN-NN03 is a frameless synchronous torque motor kit manufactured by Bosch Rexroth Indramat for the MST Synchronous Torque Motors series. Supplied as separate rotor and stator components, it is intended for direct integration into machine frames that require low-speed, high-torque rotation without intermediate gearing. Applications such as indexing tables, rotary cutters, and form-fill-seal mandrels benefit from its tight coupling to the driven shaft, which eliminates backlash and improves positional accuracy. The open geometry also permits custom bearing, seal, and cooling arrangements around the stator bore.
Heat generated in the windings is removed through a liquid-cooled jacket, so the magnetic circuit stays below its thermal limits during sustained stall torque operation. The three coils are arranged in a three-phase configuration, which produces balanced electromagnetic fields and compatibility with standard servo inverters. With an IP00 degree of protection, the motor must be installed inside an enclosure where ambient contamination and shock hazards are controlled. The stator laminations use a laminated core design that reduces eddy-current loss and increases efficiency at low electrical frequencies. Because the assembly is an open kit motor, the bearing system and mechanical housing are supplied separately, allowing unrestricted shaft diameter and axial length selection.
Electrical termination is provided through an axial outlet on the large-diameter side, and this routing keeps cables clear of moving parts while matching the machine's radial footprint. The outlet accommodates a 3.2 ± 0.2 mm cable sheath, while phase conductors use AWG 16 leads with a 1.0 mm² cross-section to handle the continuous current used for this frame size. The wires are supplied as twisted pairs to help suppress common-mode noise, and the rear side of the stator remains open for coolant manifold installation. Signal and power lines exit in an axial direction on the larger-diameter side, which simplifies cable routing on rotary tables.
