300W BLDC Three-Phase DC Brushless Motor Controller DC5V-50V No Hall Motor Drive Control Module PWM Signal Input _x000D_ _x000D_ Features: This driver is a DC three-phase brushless controller without Hall sensors. The motor operates normally even without Hall sensors. BLDC wide voltage 6.5-50V, high power 380W, DC three-phase high-speed brushless sensorless controller. Newly added PWM signal input, supports 3.3V systems. PLC 0-5V analog signal input control specifications. _x000D_ Parameter: Operating Voltage: 5-50V (Max 60V) Drive Current: Rated 16A, 25A with forced air cooling Power: Rated 200W-250W, Peak 300W (Allow operating margin) Overcurrent Protection: Yes Locked-Rotor Protection: Yes (Current automatically reduces after stall, operating intermittently) Overtemperature Protection: Yes (Power halved during overheating) Maximum Speed: 224,000 RPM (2-pole motor), 74,000 RPM (6-pole motor), 40,000 RPM (12-pole motor), 35,000 RPM (14-pole motor). Maximum power can still reach 380W, but additional cooling measures are required. _x000D_ Special Notes for External Signal Input: 1. 0-5V Input Mode: Switch to 0-5V input mode via button. Input 0-5V analog signal via terminal block to control speed. Maximum voltage must not exceed 5V. Factory default mode (ensure on-board potentiometer is set to minimum). 2. 1-4.2V Input Mode: Press the button to switch to 1-4.2V input mode. Connect the signal to the terminal block. Control speed with a 1-4.2V analog signal, not exceeding 5V. This mode is primarily for use with Hall-effect handles (remember to set the on-board potentiometer to minimum). 3. PWM Input Mode: Press the button to switch to PWM input mode. Input the PWM signal through the terminal block to control speed. Optimal amplitude: 3-5V; optimal frequency: 1K-10KHz (Remember to set the on-board potentiometer to minimum). 4. Forward/Reverse, Brake, and Stop Ports: Maintain low-level active. Connect external switch ports to ground for corresponding control. Alternatively, an external MCU can provide low-level signals. All front-row control terminals are low-voltage signals directly input to the MCU controller. Avoid contact with high-voltage or high-current sources. _x000D_ Product Specifications: 1. This driver module exhibits rapid acceleration response. Instantaneous startup current is extremely high during full-throttle power-on. Maintain sufficient margin; avoid high-voltage, high-power, full-throttle reversing starts. Additionally, braking generates significant impact forces. Do not brake during high-voltage full-speed operation, as forced operation may damage power transistors and chips. Operate only after reducing throttle to 50% or below. 2. The rated maximum voltage (60V) and maximum power (300W) are limit parameters under specific conditions. Actual application requires operating with a safety margin. Note: This driver is a DC three-phase brushless controller without Hall sensors; motors without Hall sensors can still operate normally. _x000D_ Package include: 1 xDC 5-50V 12V 24V 48V 300W BLDC Three Phase DC Brushless Motor Controller PWM No Hall Motor Control Driver Board _x000D_ _x000D_
