Product Description:

The AKM12E-BNMN2-00 is a brushless synchronous servo motor designed and manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. In automated machinery, it converts drive commands into controlled rotational movement and supplies accurate torque and speed for indexing tables, pick-and-place modules, and small gantry axes. This type of motor is commonly paired with a digital servo drive that closes the current, speed, and position loops in real time. That arrangement helps the axis respond quickly to command changes and maintain stable motion during short indexing moves.

The mechanical interface follows a NEMA flange pattern, so the motor fits common North American servo mounts without adapter plates. The square frame measures 40 mm across, which helps the unit fit into tight machine envelopes while maintaining contact with the mounting surface for heat transfer. A smooth shaft is provided for clamp or press-fit couplings that help minimize backlash in light-duty axes. Position information is supplied by a Comcoder feedback device that provides incremental signals from an optical disk with 2048 lines/rev. The standard flange format simplifies installation on compact slides and rotary tables, and the motor uses the standard customization level so its dimensions, cabling, and exterior finish follow the regular production configuration.

The motor is supplied without a brake, so holding torque must come from the drive or an external mechanical device when the axis is stopped. The encoder uses single-turn optical feedback for rotor position sensing during closed-loop operation. Drive identification can use the EPC 15T feedback type code together with Rotor Length Index 2, which corresponds to the medium rotor stack for this housing size. The e winding provides the voltage constant used with low-voltage servo amplifiers, and matching the feedback code and rotor index in the drive helps ensure that control settings correspond to the motor's electrical and feedback data.
