BP1-416 Frequency Sensitive Rheostat for 3-Phase AC Motor Starting
Product Overview
The BP1-416 Frequency Sensitive Rheostat is a professional and reliable component specifically designed for the smooth starting of 3-phase AC wound-rotor asynchronous motors. As a core device in motor control circuits, it effectively limits starting current, reduces mechanical impact, and ensures stable, efficient motor operation throughout the startup process.
Operating Principle
Essentially a three-phase reactor with high iron core loss, the BP1-416 features automatic impedance adjustment based on rotor current frequency. During startup when rotor frequency is high, the rheostat's impedance increases to restrict inrush current. As motor speed increases and rotor frequency decreases, the impedance automatically reduces, enabling smooth acceleration to rated speed without manual adjustment.
Construction & Durability
Constructed with high-quality steel core and precision copper windings
Robust durability and excellent electrical performance
Solid structure enhances resistance to vibration and harsh industrial environments
Suitable for both light and heavy-duty occasional starting scenarios
Applications & Benefits
Widely applied in motors with power ranging from 2.2KW to 2240KW
Ideal for equipment such as water pumps, air compressors, rolling mills, and mining belt conveyors
Effectively prevents motor damage caused by current impact
Extends motor service life and improves overall system stability
Complies with relevant industrial standards
Key Advantages
With its simple structure, easy installation, and automatic variable resistance performance, the BP1-416 is a cost-effective and practical choice for 3-phase AC motor starting, providing reliable protection and smooth operation for your industrial equipment.
