India Project | Cost-Effective Sensorless BLDC Control IC for Electric Pump Systems

2026-01-29

India Project | Cost-Effective Sensorless BLDC Control IC for Electric Pump Systems

1. Project Background

An Indian manufacturer of electric water pumps and fluid circulation systems sought a reliable and cost-effective controller IC for sensorless BLDC motors.

The pumps required high startup torque, anti-stall protection, and stable operation in harsh temperature environments.


2. Customer & Application Scenario

  • Country: India 

  • Customer Type: Pump & motor system manufacturer

  • Applications:

    • Water circulation pumps

    • Agricultural and industrial pump motors

  • Operating Conditions: High load, frequent start-stop cycles


3. Our Solution

We delivered a complete BLDC control solution based on JY02A, including:

  • Startup torque adjustment for heavy-load applications

  • Constant current drive to protect power devices

  • Soft start to reduce mechanical stress

  • Direction control for flexible system design

The IC’s JYKJ full-condition safe startup technology ensured reliable motor startup under all conditions.


4. Key Parameters & Line Features

  • Voltage Range: 4.5V–5.5V

  • Temperature Range: -55℃ to +125℃

  • Speed Control: Linear

  • Protection: Overload & anti-lock

  • Adaptive Control: EAI self-adjusting motor matching


5. Delivery & Customer Feedback

  • Delivery Mode: Bulk shipment with batch traceability

  • Lead Time: 10 working days

  • Customer Feedback:

    Compared with our previous solution, the JY02A controller significantly improved startup reliability and reduced failure rates in high-load pump applications.

The customer has since moved to mass production adoption.
