Product Description:
The MSM019A-0300-NN-M5-MH1 is a miniature synchronous servo unit produced by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. Intended for compact automation equipment, the motor delivers controlled rotary motion to indexing tables, compact grippers, and lab automation modules, providing precise acceleration and deceleration under drive control during short motion cycles. When paired directly with an IndraDrive controller, it converts digitally commanded current into torque and supports closed-loop positioning of lightweight mechanical axes with repeatable response.
The integrated holding brake uses electrical release, so it disengages only when current is applied and helps prevent drift on vertical or inclined shafts during power-off states. At standstill, the rotor can deliver a continuous torque of 0.16 Nm, which is suitable for keeping small inertial loads aligned without excess heating. Waste heat leaves the frame by natural convection, so no fan or liquid loop is required, and the installation should leave unobstructed airflow around the housing. For static parking, the brake supplies 0.29 Nm of holding torque to keep the axis locked without relying on the motor windings. The motor has length code A, which is the shortest build in the series and helps reduce reflected mass in fast pick-and-place gantries.
The motor has a frame size of 019, which gives it a compact flange pattern for miniature gearheads and couplings in small mechanical assemblies. Stator winding code 0300 indicates the voltage constant and nominal current used by the matching IndraDrive amplifier. A plain shaft simplifies coupling to press-fit pulleys and avoids the added machining associated with keyed designs. Because there is no shaft seal, the front bearing zone remains open, so the motor should be used outside splash zones or inside a clean enclosure to reduce the risk of lubricant washout and particulate ingress.
