Product Description:
The model AKM22H-CKSNAD-02 is a Brushless DC Servo Motor designed for demanding industrial applications. This motor is ideal for positioning tasks in industrial robots, machine tools and transfer lines. Its design ensures dynamic performance and stability when combined with digital servo amplifiers.
This AKM22H-CKSNAD-02 servo motor features permanent magnets in the rotor using neodymium-iron-boron magnetic material to enable high dynamic response. The stator integrates a three phase winding that is electronically commutated by the servo amplifier. This eliminates the need for brushes. Shaft type of this motor includes open keyways for secure mechanical connection. The stator winding temperature is monitored via an electrically isolated thermistor (PTC) with resistance values of 550 ohms and 1330 ohms. The motor operates under the climate category 2K3 with a transport temperature range of – 25 °C to + 70 °C that is limited to a maximum change of 20 K/hr. The bearing noise should be checked every 2500 operating hours to ensure longevity. This motor is finished in matt black (RAL 9005) though the coating is not resistant to solvents like trichlorethylene and nitro thinners. It delivers excellent thermal stability in environments requiring high precision.
A resolver is integrated into this Kollmorgen AKM22H-CKSNAD-02 servo motor as the standard feedback element to ensure precise position and speed control. The servo amplifiers in the SERVOSTAR series continuously monitor the resolver's signals. It accurately determines the rotor's position and supplies sinusoidal currents to the motor for smooth and efficient operation. This built in resolver provides robust and reliable feedback. Alternative feedback systems such as optical encoders or other sensor based solutions are available as options. However, these alternative systems may affect the overall motor dimensions.
