Product Description:

The MSS162J-0500-FA-N0CN-NNL5 is an open stator kit motor that Bosch Rexroth Indramat builds for the MSS Synchronous IndraDyn H Motors series. In automation cells, this type of frameless motor is pressed into a machine housing so that the drive offers direct-drive torque without a separate frame. The design supports liquid cooling, allowing the unit to maintain stable winding temperatures while occupying minimal space in high-precision rotary tables, printing drums, or semiconductor handling axes.

The permissible ambient range extends from 0 °C up to 40 °C, and reliable operation is maintained to installation heights of 1000 m. A protection level of IP00 applies because the stator is delivered without its own enclosure, so shielding is provided by the host machine. Coolant can be supplied at pressures up to 6 bar through two axial ports threaded G 1/8 and M16 × 1; the circuit must deliver adequate flow through the cooling jacket to maintain thermal stability. The winding temperature is monitored by a KTY84-130 sensor, which the drive controller reads for thermal protection. Electrical power is fed in through a preassembled connection cable that exits radially from the laminated core.

Temperature feedback comes from a KTY84-130 probe, allowing the connected drive to monitor winding heat through a linear resistance signal. The motor has an Open (Kit Motor) construction, so the surrounding machine structure must provide guarding and the final protective enclosure. All six stator fixing holes are tapped M6 to a depth of 12 mm, which helps distribute clamping force evenly around the assembly and keeps the stator seated securely in the customer-supplied housing. This mounting arrangement supports accurate integration into rotary tables and other direct-drive mechanisms that use the frameless motor as a built-in torque source.
