Product Description:

The AKM21C-ANMNC-00 Servo Motor is developed by Kollmorgen. The motor relates to the AKM Synchronous Servo Motors Series. The motor is engineered to perform well under high loading conditions.

The AKM21C-ANMNC-00 servo motor consumes 1.58 current when it is energized but not rotating which reflects how much power is needed to maintain torque at a standstill. The amount of resistance the rotor has to changes in speed is 0.11 kgcm² which is lower and is common for fast-responding, lightweight servo systems that require quick acceleration and deceleration. It is featured with an IM B5 mounting style which is an IEC standard for flange mounting and means it is designed to be mounted using a flange face that allows secure and standardized integration into machinery. It comes with a winding code of C which refers to a specific internal winding configuration and essential for matching the motor to the correct drive or controller. Without overheating the continuous mechanical power output the motor can deliver is 0.12 kilowatts. The expected lifespan of the ball bearings within the motor under standard conditions is at least 20,000 hours which suggests good durability and reliability for industrial or automation tasks.

All of its connections are shielded which reduce electromagnetic interference and they are also protected against solid objects larger than 12 mm. Its stator uses a three phase winding which is standard for efficient and smooth torque production in servo motors and ensures better performance and less vibration. The AKM21C-ANMNC-00 servo motor comes with a rated speed of 2500 rpm in which it can run continuously under rated conditions. For short periods of time it can generate maximum torque of 1.47 nm.
