Product Description:

The MTB506B1-F1A1 is a brushless servo motor manufactured by Kollmorgen for the MTC Servo Motors series. As a rotary actuator, it converts controlled electrical energy into precise angular motion, allowing CNC machines, packaging lines, and robotic axes to position loads quickly and repeatably. The unit integrates an electromechanical brake and high-resolution feedback so the drive can hold or adjust the shaft position in response to dynamic process commands in industrial automation cells. Its standard square flange simplifies integration with compatible gearboxes and couplings.

The rated mechanical output is 2.8 kW at a nominal speed of 3300 rpm. At 40 °C, the stator can sustain 11.4 N·m of continuous torque while drawing 16.7 A RMS from a 230 VAC drive. The electromagnetic design produces a back electromotive force of 41.4 VRMS/krpm, which the controller uses to predict voltage demand during acceleration. The winding resistance is 0.371 Ω, allowing current to rise quickly while remaining within the drive transistor limits. Position data come from an 8192 PPR incremental encoder, supporting tight velocity control. The motor uses a 130 mm square IEC flange with a 19 mm shaft and a 6 mm square key. Including the rear brake housing, the overall motor length is 300.5 mm, which allows placement in extended-axis assemblies.

Transient loads are supported by a peak torque reserve of 45.0 N·m, which the rotor can reach when the inverter supplies up to 74.4 A RMS for a short duration. The low rotor inertia of 0.00181 kg·m² helps the axis reverse direction rapidly while keeping servo gains moderate. A DC-released holding brake rated at 90 VDC locks the shaft when power is removed, preventing vertical loads from drifting. The 230 VAC line voltage requires suitable insulation and adequate connector clearance. These electrical and mechanical characteristics support frequent acceleration, deceleration, and positioning cycles in production machinery without requiring an oversized motor frame.
