WS55-220 DC 48V 500W CNC Brushless Spindle BLDC Motor Driver ControllerSpecification:Features:The controller can drive the DLDC motor with HALL or without HALL.The driver is based on advanced technology and be provided with high speed, high torque, low noise, low vibration, over current protection, overload protection, less phase line. protection, phase line short protection, alarm output, speed signal output,positive negative rotation control etc.This controller can be used in small equipment, Electric Power Tools, exhaust Fan, Jade grinding machine, Vibrating motor etc.With overvoltage protection, over-current protection, locked-rotor protection.Specifications:Rated voltage: 20 to 50 VDCRated current: 12ACurrent limiting: 15AMaximum speed: 20000RPM( the specific speed depends on the motor itself and load)Storage temperature: -20~+65Usage environment: Avoid direct contact with dust, fumes and corrosive gasesTemperature: 0-45Humidity:Shock: 5.9m/S2 MaximumStorage humidity: 0~95%RHSize: Approx. 9.5 x 6 x 3.5cm / 3.74 x 2.36 x 1.38inchWeight: 258gDetail:1.Two modes of speed regulation:External potentiometer: through this potentiometer speed regulation;Note: The two speed regulation can not be used simultaneously2. Speed output PG signal: There is a 5v-revolution pulse output between the port and the ground.The output frequency is set to P (Hz), the motor class logarithm is N, and the speed is F (RPM), then the output speed frequency is P=F*N/60.3. Alarm output ALM signal:There is an 5V alarm pulse output between the port and the ground.4. Positive inversion function:F/R:Fiddle the toggle switch on the corresponding side, the motor steering direction can be changed. For the toggle switch, the white part is up and down, then twang it up and down. For the toggle switch, the white part is horizontal, and the twang horizontally.5. Start-stop (two control modes):1. External switch EN: Transfer through switch.2. Side toggle switch EN: for the toggle switch, the white part is up and down, then down for the start; for the toggle switch, the white part is horizontal, then dial to startNote: You can only turn one control at the same time, one of the switches is closed, and the other one is valid.6. Locked-rotor protection:If the motor stops working, switch on the power again to start.7. Power light: Green light: power on and off8. Status light: Red light: two flashes in standby time, after starting, extinguish.9. Insulation resistance: >100M at ambient temperature and atmospheric pressure10. Insulation strength: At normal temperature and pressure, 0.5KV, 1 minutesPackage included:1 x Motor Driver Controller with cableNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
