![]() ![]() The NPN transistor BD 139 drives the output from timer IC, this output pulse duration decides the speed of DC motor, by varying the VR1 resistor we can vary the pulse output of timer. The diode D1 protects the DC motor from the back emf effect hence there is no output load effect rise. DC Motor Forward/Reverse Control: General Electronics Chat: 24: Nov 6, 2021: J: RC-single push button forward reverse motor: General Electronics Chat: 27: Jul 7, 2021: DC motor forward and reverse: General Electronics Chat: 34: Jan 19, 2021: L: Dynamic braking ideas for forward/reverse DC motor: Power Electronics: 9: Nov 29, 2020: P: Forward. ![]() The PLC implementation of this circuit should include the use of the overload contacts to monitor the occurrence of an overload condition. ![]() Figure 2 shows the simplified wiring diagram for this motor. The DC motor is connected to the supply through DPDT ( double pole double through ) switch, by changing the switch position we can get forward and reverse rotation from the DC motor because this switch interchanges power supply polarity applied to the DC motor. Figure 1 illustrates a hardwired forward/reverse motor circuit with electrical and push button interlockings. Where a leak-proof valve is not required however (e.g. In this website we already published about Speed control of DC motor with timer IC, here this circuit constructed for the basic motive to meet the forward / Reverse operation of DC motor with speed control. Even particles smaller than the spool to body clearance can over time build up and jam the spool (a phenomenon known as ‘silting’). ![]()
