WS55-180 DC 20V-50V CNC Brushless Spindle BLDC Motor Drive Controller ToolFeatures: WS55-180 is a high quality, cost-effective 3 phase BLDC motor controller. The voltage range is from 20VDC to 50VDC. The controller can control the DLDC motor with or without hall. The driver is based on advanced technology and be equipped with high, high, low noise, low vibration, over-current protection, overload protection, less phase line. Protection, short phase line protection, alarm output, signal output, positive negative rotation, etc. This controller can be used in small equipment, electric tools, exhaust fan, Jade grinder, vibration motor, etc. External potentiometer control/external voltage control. With surge protection, surge protection, impeller blocked protection. Specifications:Rated Voltage: 20 to 50 VDC Rated Speed: 10A Current Limit: 15A Temperature Limit: 20000 rpm (specific depends on the motor itself and the load) Storage Temperature: -20 °C - +65 °C Usage Environment: Avoid direct u with dust, fumes and corrosive gases Temperature: 0-45 °C Voltage: lt; 80%, no frost, no frostShock: 5.9m/Storage humidity: 0 - 95% RHRoume: 9.5*7*3.5cm / 3.74*2.76*1.38inWeight: 260gDetails:1. Two Adjustment Modes:External Potentiometer: With this potentiometer adjustment; External voltage: external voltage regulation 10VDC; Note: Two adjustments cannot be used at the same time2. PG output signal: there is a 5v pulse output between the port and ground. The output frequency is set to P(Hz), the logarithm of the motor class is N, and F(RPM), then the output frequency is P = F * N/60.3. ALM Alarm Output: There is a 5V alarm pulse output between the port and ground.4. Positive inversion function: F/R: box two-position switch on the corresponding side, the motor control direction can be changed. Two-position switch, the white part is up and down, then scrolls up and down. Two-position switch, the white part is horizontal and the bellies are horizontal.5. Start-stop (two control modes):1. EN external switch: transfer through the switch.2. Side toggle switch EN: two-position switch, the white part is up and down, then down to start; For the two-position switch, the white part is horizontal, then select to startNote: you can only turn on one control at a time, one of the switches is closed, and the other is important.6. Rotor protection locked: if the motor stops working, turn the power back on to start.7. Power Light: Green Light: On and Off8. Status light: red light: two flashes during standby, after starting, turn off.9. Insulation resistance: &;100M at ambient temperature and atmospheric pressure10. Insulation strength: under normal temperature and pressure, 0.5kv, 1 minute Wiring Diagram:Package Included:1 x Motor Drive Controller with Cable
