It comes with a metal shell and a connective label, making it very simple to install and use. It has a potentiometer with an adjustable speed switch and a button switch. Note: DO NOT REVERSE POSITIVE AND NEGATIVE POWER LOADS. THIS WILL DAMAGE THE CONTROLLER. TO CHANGE THE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF THE MOTOR. Remainder Before you attempt to wire the controller, make sure the power is off

9-60V 20A DC Motor Speed Controller Experience precise control with our DC Motor Speed Controller - a versatile and reversible PWM switch featuring a metal shell and user-friendly connective label for effortless installation. The DC Motor regulator has a linear potentiometer with adjust speed switch function, and button switch function. The controller has an operating frequency of 25KHZ and reverses polarity protection. The motor running condition adjustment is given by: Forward, Stop and  Reverse. The Input Current required is usually larger than the motor's operating current and the output current is determined by load size. Note:1. This governor is used for DC brushed motors.2. Not suitable for DC brushless motor speed; can not be used as a regulator or regulator!3. The motor can be divided into positive and negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence. DO NOT REVERSE POSITIVE AND NEGATIVE POWER LOADS. THIS WILL DAMAGE THE CONTROLLER. TO CHANGE THE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF THE MOTOR.Reminder:The DC motor governor is connected to the DC power supply.Never connect directly to home 110V AC.Before you attempt to wire the controller, make sure the power is off.

IRF520 MOSFET Driver Module for Arduino/ Raspberry Pi IRF520 MOSFET Driver Module for Arduino/ Raspberry Pi is a breakout board for the IFR520 MOSFET transistor. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Here is a simple breakout board for the IRF520 Mosfet. Easy hookup to your Arduino or another 3-5v microcontroller. Pulse current through a PWM pin, and use this to control a pump, LED, or other DC device at up to 24v, and ~5A. The main purpose of this IRF520 MOSFET Driver Module Board compatible with Arduino is to provide a low-cost way to drive a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw terminals are provided to interface with your load an external power source. An LED indicator provides a visual indication of when your load is being switched. How to use PWM Adjustment MOS Drive Board? The simplest way of explaining how this little board works is as below: You connect the power for the device you want to control the Vin and GND. You connect your device to the V+ and V- screw terminals. When the SIG line is HIGH, a little LED lights up, and the GND is ‘connected’ to the V-. When the SIG line is LOW, the LED turns off, and the GND becomes ‘disconnected’ to the V-. The V+ and Vin are continuously connected. You can power this device from your Arduino, VCC goes to the 5V connection and GND to the GND pin on your Arduino. Note: Heat sinks need to be installed for loads above 1A .  Package Includes: 1 x IRF520 MOSFET Driver Module for Arduino Raspberry Pi Specifications: Operating Voltage 3.3 ~ 5V Ports Digital Level Output load voltage(V) 0 to 24 Dimensions 3 x 2 x 1cms Weight  5 grams

Big DC Motor A Big DC motor is a mechanically commutated electric motor powered from direct current (DC). It is of 2000 rpm.  The stator is stationary in space by definition and therefore its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees, which generates the maximum torque. These DC motors are mainly used in Electronic lock, Optic equipment. Replacement spare part and give your electrical and testing equipment a new lease of life. Also check Double Shaft Motor. It has two shafts that can be mounted on either side.  Read our blog explaining the insightful comparison of dc motor vs servo motor. Learn about their key differences, applications, and advantages. Package Includes: 1 x Big DC Motor Specifications: Rated Voltage 9V Speed 200RPM Weight 60gm
