Quick Details
Specifications
48 V BLDC Motor Driver 20-50VDC 1500W Brushless DC Motor Driver WS-4850
This driver is suitable for 3 Phase bldc motor with a power of less than 1500 watts. The WS-4850 driver uses a high performance special brushless DC motor driver from the United States, the controller is designed for small and medium brushless DC motors. The engine has a high speed feature, low vibration, low noise and stable operation due to the adoption of the new PWM technology.
1. Feature:
1.1 Constant voltage of 20VDC-50VDC.
1.2 PWM frequency is not less than 12 KHz.
1.3 input signal is compatible with TTL.
1.4 disk up to 45A.
1.5 Display speed.
1.6 the driver has two functions, W jumper short circuit, electric motor can operation without Hall; W jumper does not short circuit, the motor works with the hall.
1.7 Open loop speed or closed loop control. The plant is usually planned to open the ring. The user can ask to set the maximum speed of the closed loop. Users can also change the maximum speed of a closed loop to their own, but professionals need to work.
Method of operation: turn off the power, open the cover, find 1, 3, 5, 9 jumper fields. If you need a maximum of 5000 with feedback, a 5-foot short-circuit jumper. If you need a maximum of 4000 rpm. Closed, 1,3 the lintel of the leg is closed. Method of calculation: short circuit of the jumper of the accumulation field, multiplied by 1000, the maximum speed is closed. Control the YES end from 5 V to 0 V, make the closed speed from 0 to the maximum speed.
1.8 external size: 180 * 70 * 115.
2 pin description
2.1-AT, + B terminal of external DC power supply.
2.2 U end for motor AND phase.
2.3 End for the motor In phase.
2.4W end for W phase motor.
2.5 + 5 In the end for the Hall of power components.
2.6 GND end Hall of the supply components of the negative side, that is, 0 V.
2.7 Hall for the Hall components phase.
2.8 B Hall for B phase Hall components.
2.9 C HALL for the C phase Hall components.
2.10 CW end: end of the engine forward in order for the operation. Low level effective.
2.11 AGAINST CLOCKWISE end: end of the reverse engine to start. Low level effective.
2.12 YES end: to adjust the speed, generally 0-5 V, but also 0-10 V.
2.13 BRAKE end for the input brake, low turn on.
2.14 PG end for speed feedback, open collector output, the user must add 3 K to 10 K per pull resistor when used. Whether to use the user's choice.
2.15 ER end: fault output, open collector output. If So what is wine.
2.16 ACC driver potentiometer for accelerated use, acceleration time from 0 years. 1 and 5 seconds.
2.17 W jumper closed, start the Hall brushless motor. Jumper box W is not a short circuit, the launch is brushless without a hall.
3 Electrical characteristics (T = 25 & # 8451;)
3.1 Constant voltage of 20VDC-50VDC.
3.2 The maximum output current is 40A.
3.3 insulation resistance greater than 500M.
4 Working environment and parameters
4.1 cooling mode; Natural cooling or forced air cooling.
4.2 Use the environment as far as possible to avoid dust and corrosive gases.
4.3 temperature 0 degrees to + 50 degrees
4.4 humidity 40% -89% RELATIVE HUMIDITY
5. power supply
The driver can operate normally at a DC16V-DC50V supply voltage. It can use a non-regulated DC power supply, as well as a voltage-reducing transformer + bridge rectifier + filter capacitor, the capacitor may be more than 2200 mu. However, it is necessary to pay attention to the peak value of the voltage ripple rectifier is not more than 60 V.
If the voltage stabilized power source is used, you need to pay attention to the output current range of the switching power supply to be more than 50A.
Note that & # 65306;
1, to use is not regulated power supply;
2, When not regulated power is used, the output current of the power supply must be greater than 60% set driver current. When the voltage of the stabilized power supply is accepted, it must be greater than the drive current;
3, To reduce costs, two or three drivers can share the source. But should improve the rated power and the rated output current of the power source and should pay attention to heat.
4 there is no fuse inside the disc due to high current, the user must connect a 60A fuse from the outside.
Attention: Connect all the wires and adjust the NO power supply, and do not confuse the wire pole. Or the driver may be broken.
6 Problems and solutions
CW or CCW Counter as a low start level, it takes about a second for the LED from light to dark. Driver working and LED for long.
Short Phase: LED flashes twice and then long
driver connect:
