Product Description:
The MS2M02-A0FNN-KMDH1 is an ultra-compact synchronous motor from Bosch Rexroth Indramat in the MS2M Ultra Compact Motors series. A low-inertia rotor enables rapid acceleration, and heat is removed by natural convection so no auxiliary fan is required. A 23-bit optical encoder supplies high-resolution position data, and a holding brake secures the axis at power-off. Compact dimensions follow frame size 2 with frame length A, giving a short overall depth suited to tight machinery layouts.
The motor delivers 0.48 Nm of peak torque, covering small transfer and indexing loads. Its brake is electrically released at 24 V DC, permitting quick stop-and-hold cycles independent of drive current. Control electronics use a 4.75–5.25 V logic feed, and the single-/multiturn encoder restores absolute position after power-up. An M17 SPEEDCON connector and double-metal lead-wire cable speed installation and improve shielding. Acoustic output stays below 65 dB(A), while the housing carries IP65 ingress protection. A plain shaft without a sealing ring extends 22 mm for direct coupling. The three-phase winding is specified for 3000 min⁻¹, yet total mass is only 0.78 kg, easing gantry payload limits. Continuous use is allowed between 0 °C and 40 °C ambient.
Mounting follows the series interface: a 38 mm square flange, a 45 mm bolt circle, and M3 threaded holes centred on a spigot of 30 mm. The plain output shaft is 8 mm in diameter, suiting miniature couplings. Operation is possible up to 1000 m altitude before derating applies. Adequate clearance around the housing preserves acoustic and thermal limits during high-duty positioning tasks, and prevents heat soak into adjacent electronics and cable trays.
