Product Description:
The AKM21E-ENMN2-00 is a synchronous servo motor manufactured by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. Designed for closed-loop industrial positioning, it works with a matched servo amplifier to deliver controlled torque and speed in compact multi-axis equipment such as pick-and-place heads, indexing stages, and small transfer units. Its permanent-magnet construction and integrated encoder support precise motion while keeping the overall motor size minimal for space-limited machine layouts. This type of motor is commonly used where accurate starts, stops, and short move cycles are required within a compact machine footprint.
Mechanically, the motor is built on a 58 mm frame dimension, which fits mounting patterns used in small automation platforms. A rotor length of 1 balances inertia and torque for moderate load moments, while the smooth shaft simplifies coupling to gearheads or pulleys that use external clamping hubs. The stator uses winding code e, which corresponds to phase resistance and inductance values suited to mid-voltage Kollmorgen drives. Position data is provided at 2048 lines/rev feedback resolution through a Comcoder feedback system, and the EPC 15T sensor supplies incremental signals with commutation tracks to the controller. This feedback arrangement allows the drive to monitor rotor position continuously during acceleration, deceleration, and steady-speed operation.
Control electronics receive single-turn optical feedback, so multi-turn position storage must be handled at the machine level when absolute turn counting is needed after extended rotation. Because the motor ships without a brake, vertical axes or suspended loads need an external holding method when power is removed. The motor has a Standard customization level, so sealing, winding temperature class, and connector orientation follow the baseline configuration. This layout is commonly used in general-purpose servo axes where incremental feedback and a simple mechanical interface are acceptable.
