Product Description:
The AKM22C-ENM2EH-00 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. It converts drive current into precise rotary motion while maintaining commanded position and velocity profiles. The motor is suitable for indexing tables, pick-and-place heads, and small feed axes in automated equipment where controlled movement is required.
For continuous operation, the motor delivers 0.84 N·m of stall torque while drawing 1.39 Arms without causing thermal overload. When short bursts of acceleration are needed, torque increases to 2.73 N·m at a momentary winding current of 5.56 Arms, providing additional capacity for rapid starts or direction changes. A back-EMF constant of 39 Vrms/kRPM relates motor speed to generated voltage and helps determine the bus voltage needed for the intended speed range. The integrated 24 V holding brake clamps the shaft whenever power is removed, preventing vertical loads from moving without an external lock. The motor also has a torque constant of 0.6 N·m/Arms, a C winding designation, a DC resistance of 20 Ω, and six rotor poles. These electrical characteristics support smooth commutation and allow a compatible servo drive to regulate current accurately during changing load conditions.
The motor has an inductance of 35.5 mH, which shapes the current rise and supports low ripple under pulse-width modulated drive operation. Its compact frame dimension of 58 mm allows installation within confined machine spaces, while dual Molex connectors provide convenient cable connections. A thermal time constant of 9 min indicates how quickly winding temperature responds to sustained loading, giving the drive time to reduce current before temperature limits are exceeded. The model uses rotor length index 2 and has a smooth shaft without a shaft seal. This shaft configuration supports clamping couplings and gearbox connections in clean areas where additional protection against contamination is unnecessary.
