To reduce shaft speeds, many DC motors are paired with a gearbox. This helps to reduce the motor’s shaft speed, and increase the torque output of the motor. In most cases, torque is increased by the ratio of the gear reduction, minus any losses in the gearbox.
Why do DC motors need speed control?
DC Motors plays an important role in energy conversion process. It is a machine which converts electrical energy into mechanical energy. In mechanical system, speed varies with number of task so speed control is necessary to do mechanical work in a proper way. It makes motor to operate easily.
What gear is a motor?
A gearmotor is an all-in-one combination of an electric motor and a gearbox. This makes it a simple, cost-effective solution for high-torque, low-speed applications because it combines a motor with a gear reducer system.
What is in a DC motor?
A DC motor consists of an stator, an armature, a rotor and a commutator with brushes. Opposite polarity between the two magnetic fields inside the motor cause it to turn. DC motors are the simplest type of motor and are used in household appliances, such as electric razors, and in electric windows in cars.
What is the working principle of gear motor?
A gearbox uses mechanical advantage to increase output torque and reduce RPM. The motor’s shaft is feed into the gearbox and through a series of internal gearing provides the torque and speed conversion. Our gearboxes are available in a variety of sizes and gear ratios to meet a wide range of torque requirements.
What is an AC gear motor?
An AC gear motor is a motor that is coupled with a gearbox or transmission. A gear motor adds mechanical gears to change the speed and torque of the motor for a particular application. … AC gear motors have different voltage, RPM range and max torque, be sure to check the name plate for exact specifications.
