What is a variable speed trigger?
What is a variable speed trigger?
A variable speed trigger mechanism that allows a user to reverse a direction of a motor and supply variable amounts of power to the motor using a single trigger mechanism. In a second motion, the user can actuate the same trigger and apply variable amounts of power to the motor.
How does a variable speed switch work?
It works through the regulated activation of a field coil, which generates a magnetic field that is transmitted to the input rotor, which in turn transmits it to the output rotor. The higher the intensity of the magnetic field, the higher the speed and torque that are transmitted.
What does a variable speed drill do?
Speed: A variable-speed drill with an adjustable clutch gives you versatility for drilling different materials and using a variety of bits. Drilling softwood, hardwood, metal and masonry all require different speeds and torque, or rotational force. Harder materials and larger bits require lower speeds and more torque.
How do you use a drill speed?
Setting 1 is low speed/high torque and is best for driving screws. Setting 2 is a medium speed/torque and can be used for drilling or driving. Setting 3 is the highest speed and is meant for drilling or driving fasteners.
Which motor is used for variable speed?
For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide speed range, low heat and maintenance-free operation. Stepper Motors offer high torque and smooth low speed operation.
How do you test a variable speed switch?
PLACE RED LEAD OF VOLT METER ON CENTER TERMINAL OF THE FEED RATE SWITCH. PLACE BLACK LEAD ON A SUITABLE GROUND. WITH KEY IN THE “ON” POSITION AND P/F DRUM SWITCH IN THE FORWARD POSITION, VOLTAGE SHOULD VARY SMOOTHLY BETWEEN APPROX. 1-3.5 VOLTS D.C. AS THE SWITCH IS DIALED UP AND DOWN.
Do all drills have variable speed?
Today’s drills usually have a variable speed trigger, meaning that the harder you squeeze, the faster the electric motor spins the drive shaft. Cheaper models run at a single top speed, but pricier models offer between two and four maximum speed settings, usually ranging between 200 and 2,000 rpm.
What Does 1 and 2 mean on a drill?
Setting 1 is low speed/high torque and is best for driving screws. Setting 2 is a medium speed/torque and can be used for drilling or driving. These are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque and the larger the fastener that can be driven.
How do you increase drill torque?
How to Set the Torque Setting on a Drill
- Find the arrow on the top of the drill and the numbers on the torque adjustment ring.
- Rotate the torque ring between numbers 1 through 4 if you are driving in small screws.
- Turn the torque ring between numbers 5 through 8 settings, if you are driving screws through soft woods.
