48V BLDC Motor Driver 20-50VDC 1500W Brushless DC Motor Driver WS-4850

 
 
 

This driver fit for 3 Phase bldc motor with power less of 1500W. WS-4850 driver uses the high performance special brushless DC motor driver chip from the United States, the controller is suitable for small and medium-sized brushless DC motor drive. the motor has feature of high running speed, small vibration, low noise and stable operation due to adoption of the new PWM technology.

 

1. Feature:

1.1 DC voltage 20VDC-50VDC.

1.2 PWM frequency is not less than 12KHZ.

1.3 input signal compatible with TTL.

1.4 drive current up to 45A.

1.5 speed display.

1.6 the driver has two functions, W jumper shorted circuit, electric motor could operation without Hall;  W jumper non-shorting circuit, motor running with hall. 

1.7 speed open loop or closed loop control. The factory is generally set to open ring. User can ask to set the maximum speed of closed loop. Users can also change the maximum closed loop speed by their own, but should be operated by professionals.

Operation method: disconnect the power supply, open the lid, find 1, 3, 5, 9 jumpers field. If you need a maximum of 5000 closed-loop,  5 foot jumper short circuit. If need the maximum 4000 rpm closed-loop, 1,3 jumper foot shorted. Calculation method: short circuit jumper field accumulation multiplied by 1000, is maximum closed-loop speed. Control DA end from 5V to 0V, make closed-loop speed from 0 to the maximum speed.

1.8 exterior dimension: 180*70*115.

 

 

2 pin description

2.1 -AT, +AT terminal for external DC power supply.

2.2 U end for the motor U phase.

2.3 V end for the motor V phase.

2.4 W end for the motor W phase.

2.5 +5V end for Hall components power.

2.6 GND end Hall components power negative side, that is, 0V.

2.7 A HALL for A phase Hall components.

2.8 B HALL for B phase Hall components.

2.9 C HALL for C phase Hall components.

2.10 CW end: the end of motor forward to enable the operation . Low level effective.

2.11 CCW end: the end of motor reverse running enable. Low level effective.

2.12 DA end: for the speed adjusting, generally 0-5V, but also 0-10V.

2.13 BRAKE end for the brake input, low level enable.

2.14 PG end for the speed feedback output, open collector output, the user should add 3K to 10K on the pull resistor when used. Whether to use user selection.

2.15 ER end: for the fault output, open collector output. If Pass that there is a fault.

2.16 ACC potentiometer of driver for accelerated use, the acceleration time from 0. 1 and 5 seconds.

2.17 W jumper shorted, running Hall brushless motor. Jumper field W non-shorting circuit, running brushless motor without hall.

 
 

3 Electrical characteristics (T=25℃)

3.1 DC voltage 20VDC-50VDC.

3.2 output maximum current 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 degree to +50 C degree 

4.4 humidity; 40%-89%RH 

 

5.power supply

The driver can work normally at supply voltage DC16V-DC50V. It can use non-regulated DC power supply, as well as transformer step-down voltage +bridge rectifier + filter capacitor, capacitor can be more than 2200 mu F. However, attention should be made to the peak value of the rectifier voltage ripple is not more than 60V.

If the voltage stabilized power supply is used, it is necessary to pay attention to the output current range of the switching power supply to be more than 50A.

Please note that:

1 Best to use a non-regulated power supply;

2 When the non-regulated power supply is used, the output current of the power supply should be greater than 60% of the set current of the driver. When the voltage stabilized power supply is adopted, it should be more than the drive current;

3 To reduce costs, two or three drivers can share a power. But should improve the rated power and rated output current of power supply and need to pay attention to heat.

4 There is no fuse inside the drive because of the large current, user need to connect the 60A fuse outside.

 

Attention: Connect all the wire and adjust under NO power, and don't reverse the wire pole. or the driver may be broken.

 

 

6 Trouble and solution

CW or CCW terminal as low level start, it takes about a second for Led from light to dark. Driver working and led light for long.

Short of Phase: LED flashing two times and then long dark, check the Hall signal.

Stall: LED flashing five times and a long dark. Check the Hall signal, check whether the load is stuck. If motor lines have short circuit.

Over current: LED shining three times and a long dark. Check the Hall signal, check whether the load is stuck. If motor lines have short circuit.

Low voltage: led shining seven times and a long dark. Check power supply voltage.

No running after the start: led shining six times and a long dark. Check if wiring is correct.
