PMBZQ-142 BP4-50013 Frequency Sensitive Rheostat Motor Starting Resistor
The PMBZQ-142 BP4-50013 Frequency Sensitive Rheostat is a high-performance motor starting resistor specifically designed for wound-rotor asynchronous motors. It integrates advanced frequency-sensitive technology to achieve smooth, efficient, and safe motor startup, effectively solving the problem of excessive inrush current during startup and protecting motor components from damage.
Core Functionality
As a core component of motor starting systems, this rheostat features an adaptive resistance adjustment function. Its impedance automatically changes with the frequency of the motor rotor current:
During motor startup, when rotor current frequency is high, the rheostat presents high impedance to limit inrush current and enhance starting torque
As motor speed increases and frequency decreases, the impedance gradually reduces, realizing stepless startup and ensuring stable operation transition
Construction & Durability
Constructed with high-quality materials, the PMBZQ-142 BP4-50013 boasts excellent heat resistance and electrical stability. Its internal structure adopts modular coil layout and integrated anti-corrosion housing, which is compact, easy to install and maintain, and suitable for harsh industrial environments including metallurgy, mining, construction, and chemical industry applications.
Performance Specifications
This frequency sensitive rheostat is perfectly compatible with medium and high-power motors (30~100kW), with strong load-bearing capacity and reliable performance. It requires no manual adjustment, reducing operation complexity and maintenance costs, while extending the service life of the motor and supporting frequent startup working conditions.
Application Benefits
With stable performance, energy-saving advantages and wide application scope, the PMBZQ-142 BP4-50013 is an ideal supporting component for motor starting, providing reliable protection and efficient operation guarantee for industrial production equipment.
