This motor packs a punch with a maximum torque of 46 Nm and a small moment of inertia for quick reaction speeds. The armature resistance adds to the power, coming in at 0.84 ohms.
The FANUC A06B-0239-B100 motor's impressive capabilities include a maximum rotational speed of 3000 revolutions per minute and an ultra-responsive pulse coder, allowing accurate positioning with a frequency of 200 Hz.
The A06B-0239-B100 motor boasts a 2.5 kW power output. While consuming 4.5 A of current, it is important to monitor the motor for any unusual increase in temperature due to abnormal currents to ensure maximum efficiency and device longevity by providing thermal protection.
With an improved three-phase voltage supply of 400 to 480V and a frequency range of 50/60 Hz, this motor provides excellent torque capabilities while maintaining low rotor inertia.
Engineers can rely on this FANUC model A06B-0239-B100, which has an insulation class of F and a power factor of 99%. Its waterproof connectors, coupled with its exclusive stator seal, provide unbeatable protection from liquids like a coolant for maximum assurance.
Operating the model A06B-0239-B100 at temperatures beyond its specified range can overwork it, leading to decreased performance. To ensure optimal operation of your motor, keep its ambient temperature between -10 and 40°C, lowering output power if necessary for extra protection against overheating.
The A06B-0239-B100 motor's capability to function efficiently at an altitude of 1,000 meters is not affected by the change in attitude. To ensure maximum performance even at great heights, you should take into consideration a temperature drop of 1°C per 100 m beyond this limit when operating.
Before operating, measuring the winding and insulation resistances of motors that have been in storage for an extended period is essential. Such resistance checks can be critical as prolonged non-use may cause deterioration of the motor's condition.
Proper measures must be taken to ensure a motor's lasting and reliable performance in storage. Be sure to place the unit in an area free from moisture and at room temperature for optimal preservation; additionally, store it with its shaft held horizontally and the terminal box facing up for additional precautionary protection.
