Product Description:

The MSM019B-0300-NN-M5-ML1 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MSM IndraDyn S Synchronous Motors series. Designed for compact positioning axes and feed applications, the unit converts electrical energy into precise rotary motion in automated machines and handling systems. In a servo loop, it delivers controlled speed and torque so that small grippers, indexing tables, or sensor stages can follow programmed motion profiles with minimal overshoot and repeatable accuracy. Its compact form also suits assemblies where mounting space is limited and quick response is more important than high continuous output. This operating profile is useful in compact transfer units, metering assemblies, and other small servo-driven stations where smooth motion and repeatable settling are required.

The motor uses an electrically released brake, so the spring-applied mechanism remains engaged until power is applied to release it. The holding brake provides up to 0.29 Nm of static torque, helping vertical or vibration-prone axes remain fixed when the drive is disabled. At standstill, the rotor can continuously deliver 0.32 Nm of torque, which is suitable for lightweight mechanical loads without overheating. Heat leaves the frame through natural convection, so no external fan or liquid circuit is required and installation should allow free airflow around the housing. Because cooling relies on ambient air around the housing, tightly enclosed mounting spaces can limit thermal dissipation during continuous operation. Frame size 019 sets the flange and shaft geometry for standardized miniature gearboxes and other compact drive components.

The active magnetic length uses the compact B code, which keeps rotor inertia low and supports fast acceleration on short-cycle axes. The short active length also helps reduce moving mass, which benefits rapid direction changes and frequent indexing sequences. As a synchronous motor, the unit maintains close coordination between the rotating field and rotor position, which supports stable servo response at small displacements. Winding code 0300 sets the resistance and inductance values used by the matching drive parameter set. That electrical match helps the amplifier regulate current smoothly during start-stop motion and short positioning moves.
