2. Power tool - Wikipedia

   en.wikipedia.org/wiki/Power_tool

   The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Tools directly driven by animal power are not generally considered power tools. Power tools can produce large amounts of particulates, including ultrafine particles. Airborne particulate matter is a Group 1 carcinogen.

3. Electronic test equipment - Wikipedia

   en.wikipedia.org/wiki/Electronic_test_equipment

   Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.

4. Electric motor - Wikipedia

   en.wikipedia.org/wiki/Electric_motor

   An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

5. Tachometer - Wikipedia

   en.wikipedia.org/wiki/Tachometer

   A tachometer that can indicate up to 7000 RPM (left) A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. [1] The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are ...

6. Electronic speed control - Wikipedia

   en.wikipedia.org/wiki/Electronic_speed_control

   An implementation is described in a whitepaper by Zilog on an ebike hub motor controller [5] for a 200 W, 24 V brushless DC electric (BLDC) motor. [6] P.A.S or PAS may appear within the list of components of electric conversion kits for bicycles, which implies Pedal Assistance Sensor or sometimes Pulse Pedal Assistance Sensor. Pulse usually ...

7. Universal testing machine - Wikipedia

   en.wikipedia.org/wiki/Universal_testing_machine

   Typical lectromechanical Universal Testing Machine Test fixture for three point flex test. A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing ...

8. Electric motor brake - Wikipedia

   en.wikipedia.org/wiki/Electric_motor_brake

   The disadvantage of this feature is that it wears the brushes prematurely when compared to non-brake tools. The first use of an electric brake on a tool was that of the miter saw, invented in 1964 by Ed Niehaus, a tool engineer for Rockwell Tools. Since then, a number of manufacturers have incorporated brakes into their power tools.

9. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   A multimeter can use many different test probes to connect to the circuit or device under test. Crocodile clips, retractable hook clips, and pointed probes are the three most common types. Tweezer probes are used for closely spaced test points, as for instance surface-mount devices. The connectors are attached to flexible, well insulated leads ...
