Product Description
The durable and efficient Mitsubishi HC-LP52B AC brushless servo motor delivers swift, controlled motion with its low-inertia design. It typically runs at 2000 r/min, peaking at 3000 r/min and momentarily reaching 3450 r/min for high-speed demands. Suitable for medium-capacity applications, this 1 kVA motor features an electromagnetic brake for precise stops and safety, outputting 18.4 kW/s with a standard 3.2 A current (9.6 A peak). Its enclosed, non-ventilated IP65-rated casing, complete with an oil seal, protects against dust and water, ensuring reliable operation.
Is Your Device Showing These Signs?
The Mitsubishi HC-LP52B servo motor commonly experiences issues such as resolver feedback errors, often resulting from damaged resolver windings or faulty resolver signals. Overheating due to excessive load or inadequate cooling is a frequent problem, leading to decreased performance and potential winding insulation breakdown. Bearing failures occur due to wear and tear, causing increased noise and vibration. Power supply issues and drive incompatibility are also common, leading to operational faults and requiring careful diagnosis of the servo drive and power source. Winding shorts and open circuits within the motor stator are also observed, necessitating motor rewinding or replacement.
