Product Description:

The MS2M02-A0FNN-KMDH0 is an ultra-compact servo unit produced by Bosch Rexroth Indramat for the MS2M Ultra Compact Motors series. Identified by frame size 2 and short frame length A, the motor belongs to the manufacturer’s Product Group of Ultra Compact Motors aimed at densely packed automation cells. It provides low-inertia rotary motion for indexing tables, pick-and-place heads, and miniature gantries, translating drive commands from electronic controllers into precise shaft rotation while occupying minimal panel space.

The drive electronics accept a 3x AC 230 V mains and operate reliably within the 4.75 to 5.25 V logic range used by the encoder. Heat is removed through natural convection, so external blowers are unnecessary. It produces 0.16 Nm at standstill and reaches 0.48 Nm for short acceleration bursts, with the housing sealed to IP65 against dust and water jets. All ratings apply between 0 and 40 °C, and airborne noise is limited to 65 dB(A).

Mechanical integration is straightforward. The mounting face presents a 45 mm bolt circle, a 38 mm flange, and a 30 mm spigot that centers the housing. The plain shaft, without a sealing ring, measures 8 mm in diameter and 22 mm in length, and an M3 tapped thread simplifies coupling devices. Total mass is only 0.57 kg, supporting rapid reversals from the 3000 min⁻¹ winding. SPEEDCON M17 connectors and a double-cable metal lead set route power and encoder signals, while operation is permitted up to 1000 m altitude. The 23-bit optical single/multiturn encoder supplies absolute feedback, and no holding brake is installed.

This model is eligible for same-day shipping when time is critical. Quotations issued for the MS2M02-A0FNN-KMDH0 remain valid for 30 days, simplifying budget approvals.
