Product Description:

The Q2AA18750LBF34 is a servo motor built by Sanyo Denki for the Q SANMOTION Servo Motors series. It is intended for positioning or speed-regulated axes in automated production lines, where closed-loop drives must deliver repeatable motion while staying within compact mechanical envelopes. As a medium-inertia model, the motor balances acceleration capability with load-matching stability, allowing it to operate with a wide range of gearheads, ball screws, or direct-drive loads.

The motor attaches to machinery through a flange that measures 180 mm, providing a consistent interface for compatible gearboxes and mounting brackets. Its nominal mechanical power reaches 7.5 kW, so the unit can drive sizable conveyors, extruders, or press feeders without exceeding its thermal limits. A peak shaft speed of 3000 rpm establishes the upper operating speed and supports quick indexing moves when the connected mechanism permits them. The 200 V motor winding is suitable for connection to compatible three-phase servo drives supplied from 200 VAC mains. The medium-inertia rotor reduces speed fluctuations when coupled to loads with a high moment of inertia while remaining responsive enough for pick-and-place or tool-change sequences.

An integrated 90 V brake holds the shaft when power is removed, helping prevent drift on vertical axes or during emergency stops. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, supporting stable torque production in most indoor factory environments. The motor tolerates up to 90% relative humidity when condensation is prevented, making it suitable for humidity-controlled production areas. The holding brake requires an appropriate power supply and control circuit so that it releases during commanded motion and engages when the axis stops. Proper ventilation around the housing is necessary to prevent accumulated heat from reducing the motor’s continuous operating capability.
