Electric motors provide the mechanical energy for the correct operation of tools and machinery. With this in mind, we invite you to find out how single-phase gear motors work and their main features.
What are single-phase gear motors and what is their treatment?
According to the number of feeding phases used by electric motors to provide energy, we can distinguish between single-phase, two-phase and three-phase motors that have different powers to feed a great diversity of machines and tools.
When we talk about single-phase gear motors, we are referring to motors that transform electrical energy into mechanical energy through single-phase electrical power.
That is to say, the wiring of the piece is made up of only two wires that operate with a potential of up to 3Kw. This main characteristic makes them largely used for minimum powers, unlike other electric motors that have a higher voltage.
However, today there are certain single-phase motors whose power can reach up to 10 hp and operate through a 440V connection. Alongside with power, they always require the use of a capacitor for their starting due to the impossibility of creating a rotating magnetic field since they only do it by means of an alternating field.
Uses of single-phase gear motors and some possible problems
Single-phase gear motors are recommended for basic electrical applications. Therefore, they are usually used in applications where the power supply is produced directly between the equipment and the network, such as in homes, commercial stores, small companies that do not work with large machinery such as refrigerators and commercial cold displays, offices, among others.
Among the most common uses of this type of motor we can highlight household appliances, commercial and home refrigeration, heating and ventilation, opening and closing systems on parking doors, utensils or power tools used in everyday life such as hammers, drills and others.
n the other hand, its use is recommended for systematic and continuous operations since they do not have internal brushes that wear out easily due to the normal friction of the parts as it usually happens with other mechanical parts.
Although single-phase gear motors have their problems like any other type of gear motor, it is important to note that they are easy to repair and care for, as well as being very affordable. The most common problems that arise with them are:
Wear/breakage of the powertrain gear teeth.
Wear of the pitch-shaft hole, making it larger and causing play in the movement of the gears.
Engine malfunction due to electrical failure.
Lack of lubrication or use of improper lubricants.
Noise due to deformations in the gears or to poor manufacturing of the gears.
DOLIN’s experience in single-phase gear motors and success stories
At Dolin, we have four decades of experience and work making single-phase motors to find the perfect movement and power to suit the specific demands of each of the businesses managed by our customers.
Our goal is to develop precision single-phase gear motors and parts that fit perfectly to small dimensions under today’s most demanding quality standards.
Among our success stories, we can highlight a project developed for a renowned company in the hospitality sector , dedicated to the manufacturing and marketing of machines with many years of experience, which had problems related to the supply of orders to its customers in terms of lack of time and delays in deliveries.
In addition, the machinery was exposed to degradation and wear as a result of the high temperatures to which it is continuously subjected due to the proximity.
The challenge was to increase the mechanical resistance of the equipment to high temperatures, using specific lubricants and motors with thermal protection.
The result was a safety system based on temperature control that prevented the engine and supply from breaking down in time that so affected the company.
We also took part in another project, in which our team of engineers worked to improve the density control system for slushers and chillers. in order to operate with more efficient, reliable and silent machines.
