Stepper motor controllers send pulse signals to drivers, which control the function of stepper motors. They offer additional control over motor functions, including microstepping and multi-axis control. Some controllers can control several motors from one point. Controllers must be matched to the appropriate motor and driver type, which can be bipolar or unipolar. Stepper motor […]
Scooters are motor-powered vehicles with two wheels and a step-through frame. They are popular in urban areas due to low maintenance costs and ease of handling. The first scooters were developed for military use in the US, and later adapted in Italy as the Vespa. Scooters are subject to strict emissions standards in the US, […]
Wound rotor motors have reduced speed control and current ratings, but increased torque during startup. They have rotors with three wire windings terminated with slip rings, allowing for variable resistance during startup, reducing current consumption and increasing available torque. This makes them ideal for high inertia loads, such as large ventilation fans, conveyor belts, and […]
A traction engine is a portable steam engine that can travel on highways and other firm surfaces. It was used for agricultural and industrial applications in the 19th century, but declined in popularity with the rise of gasoline-powered equipment. A traction engine is a type of portable steam engine that is similar to a locomotive, […]
Prop engines power propeller-driven aircraft and typically use high octane gasoline. They are similar to car engines and require annual inspections to prevent accidents. Carb heat controls prevent fuel from freezing at high altitudes. A prop engine is commonly a piston-driven internal combustion engine that powers a propeller-driven aircraft. With the exception of turboprop aircraft, […]
Motor graders are versatile machines used for excavation, fine finishing, and road construction. They have a blade controlled mechanically or hydraulically, and can be used for dirt road maintenance and foundation pads. Advances in technology have made them more versatile and able to replace other equipment. Motor graders are used in excavation and fine finishing […]
Motor oil is essential for engine care, lubricating moving parts and extending engine life. It should be changed every 3,000 miles and topped up with the same type of oil. Petroleum-based oil is cheaper but synthetic oil is superior for high performance. Viscosity is important and varies depending on climate. Other factors to consider include […]
Motorized scooters are affordable and eco-friendly vehicles that are popular in warm climates. They have safety features and manual controls, and riders should wear helmets and eye protection. Practicing in a safe area before riding in traffic is recommended. Motorized scooters are motorized vehicles that have two wheels. Also known as electric mopeds or scooters, […]
The ball bearing motor runs on thermal energy and can be built easily with salvaged parts. It rotates in response to high currents and can spin very fast. Safety precautions should be taken when handling it. An electrical device, a ball bearing motor runs on thermal energy, rotating in response to starting with high currents. […]
Hydraulic technology uses pressurized fluid to power machines, including cars, and is a greener alternative to traditional engines. While not yet used in car engines, hydraulic parts can assist combustion engines and create powerful force through small tubes. Key components include hydraulic pumps, cylinders, and motors. Hydraulic cylinders may one day lead to the creation […]
A motor coupler connects an electric motor to an appliance’s drive system. It uses two drive plates cushioned by a rubber shock absorber and transfers power from the engine to the transmission. The rubber absorbs shock and torque, causing wear and tear that requires replacing the entire coupler. No fastener is needed as the coupler […]
Unipolar motors are used in small devices, such as cassette decks, and have a magnetic band with one pole facing inward and outward. The microcontroller helps control functions like recording and playback. The design is simple, inexpensive, and allows for affordable prices for consumers. A unipolar motor is one of several types of small motors […]
A hydraulic motor uses pressurized fluid to drive machinery, with gears and pistons controlling torque and speed. Leakage and monitoring are concerns, but they can produce more horsepower than other motors and are used in aircraft, construction vehicles, and heavy machinery. A hydraulic motor is part of a hydraulic drive system that uses pressurized fluid […]
Steering motors were first used in the mid-1800s to help move the rudder of large ships. They act as power steering and hold the rudder in position during rough seas. Modern vessels use hydraulically actuated steering cylinders and joysticks instead of ship wheels. A steering motor is a device used to help move the rudder […]
A worm gear motor consists of a threaded gear, an interlocking gear wheel, and a motor. It amplifies the rotational force of the motor and is used in heavy industry, transportation, and small tools. The force required to drive the wheel depends on various factors, and the motor needs frequent lubrication. It is self-locking and […]
Motor neuron lesions can be caused by physical trauma, autoimmune disease, or fetal abnormalities, leading to abnormal muscle control and movement. They can affect speech, chewing, and swallowing. Lesions are divided into upper and lower motor neuron injuries, causing spasticity and flaccid paralysis respectively. Diseases affecting motor neurons can be progressive and include cerebral palsy, […]
A stepper motor circuit uses voltage pulses to rotate the mechanical shaft in discrete steps. The number of pulses and frequency determine speed, and there are three types of stepper motors: variable reluctance, permanent magnet, and hybrid. A microcontroller can be used to program the circuit for efficient control. A stepper motor circuit is a […]
Stepper motors divide rotation into steps using electromagnets and teeth on the gear. They are brushless and controlled by turning electromagnets on and off. There are three control mechanisms, and they require a constant power source. Adding more electromagnets can decrease vibration. They are commonly used in small, precise devices like CD drives and printers. […]
A submersible motor powers pumps in water wells and sump pumps. It must have watertight electrical connections and is placed at the bottom of the casing to push liquid effectively. The motor is contained within a rubber sock for protection. A submersible motor is an electric motor that can operate while submerged in water. This […]
Submersible motors power pumps in water wells and sump pumps. They must have watertight electrical connections to prevent damage. The motor is lowered into the well or pit and pushes water out, resulting in less power usage and a cooler motor. The motor is contained in a rubber sock for protection. A submersible motor is […]
