Advantages of gear motors
There are many advantages of gear motors over servo motors. These motors can achieve similar torque levels as larger gearless motors at a fraction of the weight. They can also reduce vibration, making them ideal for applications with high inertial loads. Geared motors can also be downsized and are more stable than gearless motors.
The main advantage of gear motors is that they require less maintenance than their belt and pulley counterparts. The gearbox is directly connected to the motor without needing external connections or adapters. They can also be lightweight and require little maintenance. However, they can be costly, especially in India. Therefore, they are often used in industrial environments and low-speed applications. Furthermore, the advantages of gear motors far outweigh the disadvantages.
How does a gear motor work?
A gear motor has two parts: the rotor and the output shaft. When hydraulic pressure is applied to the gear teeth, the output shaft rotates, producing torque. Two gears, one keyed to the output shaft and one acting as an idler gear, each attempt to move the rotor in its preferred direction. The rotor is turned by the rotating shaft, while pressurized oil passes through the inlet of the gear motor.
The principle behind the gear motor is very simple. The rotor spins at low speed and produces huge torque. Gear motors work on the same principle as electronic clocks. A series of large gears reduces the output speed of the rotor, which produces torque and powerful force. In most cases, gear motors have two speeds: normal speed and stall torque.
A simple DC motor uses many coils wound around an iron core. Each coil is connected to a commutator, which in turn powers it. As a result of the movement, magnets are introduced into the coil. The next coil is magnetized and moved, creating torque. In this way, the gear motor is efficient and smooth. If you want to design a machine that can handle a lot of inertial loads, then a gear motor is the right choice for you.
