Compact threephase BLDC motor controller, wide input 6–26V, designed for reliable, power speed control of air pumps, water pumps, oil pumps, fans and other industrial devices driven by threephase brushless motors. Key benefits Plugandrun operation: controller begins working as soon as power is applied; no external control signal required for basic operation. Simple, precise speed control: choose either stepless potentiometer control or convenient singlebutton control to match your application and operator skill. Improved process stability: supports acceleration/deceleration profiles and poweron memory so equipment returns to the previous speed setting after power interruption. Compact, power design: small physical size with performance suited to a wide range of industrial BLDC motor applications. Main features Input voltage: wide 6–26V compatibility for flexible battery or DC supply use. Control types: Singlebutton model: singlebutton control with 100level switching, adjustable acceleration and deceleration, and builtin power memory function. Potentiometer (governor) model: stepless speed regulation using an external potentiometer or 0–4.5V analog control signal. Motor type: threephase brushless (BLDC) controller optimized for power, compact installations. No external signals required for operation: powers and runs upon DC supply; external signal inputs available for analog control when using the potentiometer model. Compatibility and application Designed specifically for development and control of threephase brushless motor driven devices such as: Air pumps and aeration systems – stable speed control for consistent airflow and duty sequencing. Water circulation and transfer pumps – adjustable flow and softstart/stop for system protection. Oil lubrication pumps and industrial fans – reliable duty cycling with memory of last set speed after power loss. Suitable for integration into industrial control equipment, OEM machinery, and retrofit projects that use BLDC motors and require compact, power controllers. What makes it stand out Dual control options (singlebutton or potentiometer/analog) let you choose simple discretespeed operation or fully stepless analog control without changing controller hardware. Memory and soft acceleration/deceleration reduce mechanical stress and improve component lifetime. Wide 6–26V input range and compact package enable deployment in diverse systems with limited space. Basic specifications (as provided) Controller type: threephase brushless (BLDC) motor controller Input voltage: 6–26V DC Control modes: singlebutton (100level switching, acceleration/deceleration, memory) or potentiometer/governor (stepless via potentiometer or 0–4.5V analog signal) Typical applications: air pumps, water pumps, oil pumps, fans, and other industrial control electric tools using threephase brushless motors Example application scenarios 1) Small industrial ventilation: Install the singlebutton model on a compact fan assembly to allow operators to switch quickly among 100 discrete speed levels and retain the lastused speed after a power cycle. 2) Circulation pump control in a processing line: Use the potentiometer model with a 0–4.5V analog input from a PLC or manual potentiometer to achieve smooth, stepless flow adjustments and soft start/stop profiles. 3) Lubrication or dosing pump integration: Leverage the controller's compact, power design to bulky drive electronics, providing precise speed control and powermemory recovery after outages. Ordering notes Select the control variant required for your installation: singlebutton model for discretelevel, memoryenabled control; potentiometer/governor model for analog, stepless speed control (0–4.5V input supported).
