Company Introduction The Reasons Why You Choose Golden MotorGolden Motor has been a leading manufacturer of high power BLDC motors and controllers for more than 12 years. Electric motors are core components to make electric propulsion outboards. We had started conversion of used gasoline outboards to electric version by replacing combustion engines with BLDC motors about 9 years ago . We have gained in-depth experience and knowledge about gasoline outboards from this conversion business, and learnt its pros and cons. In the end, we decided to completely re-design electric propel outboards to address the issues and weakness areas we found from existing gasoline outboards, and to best make use of full advantages of our high efficiency (>90%) and durable (>20000 hours of working life) BLDC motors. The idea is to help the environment, cut down on noise and save heaps of money in maintenance. Boats with EZ Outboard can sit all winter and won’t require winterization and oil changes, no maintenance or only minimum maintenance is required.

What Is a Gear Motor?

A gear motor is an electric motor coupled with a gear train. It uses either DC or AC power to achieve its purpose. The primary benefit of a gear reducer is its ability to multiply torque while maintaining a compact size. The trade-off of this additional torque comes in the form of a reduced output shaft speed and overall efficiency. However, proper gear technology and ratios provide optimum output and speed profiles. This type of motor unlocks the full potential of OEM equipment.

Inertial load

Inertial load on a gear motor is the amount of force a rotating device produces due to its inverse square relationship with its inertia. The greater the inertia, the less torque can be produced by the gear motor. However, if the inertia is too high, it can cause problems with positioning, settling time, and controlling torque and velocity. Gear ratios should be selected for optimal power transfer.
The duration of acceleration and braking time of a gear motor depends on the type of driven load. An inertia load requires longer acceleration time whereas a friction load requires breakaway torque to start the load and maintain it at its desired speed. Too short a time period can cause excessive gear loading and may result in damaged gears. A safe approach is to disconnect the load when power is disconnected to prevent inertia from driving back through the output shaft.
Inertia is a fundamental concept in the design of motors and drive systems. The ratio of mass and inertia of a load to a motor determines how well the motor can control its speed during acceleration or deceleration. The mass moment of inertia, also called rotational inertia, is dependent on the mass, geometry, and center of mass of an object.

Applications

There are many applications of gear motors. They provide a powerful yet efficient means of speed and torque control. They can be either AC or DC, and the two most common motor types are the three-phase asynchronous and the permanent magnet synchronous servomotor. The type of motor used for a given application will determine its cost, reliability, and complexity. Gear motors are typically used in applications where high torque is required and space or power constraints are significant.
There are two types of gear motors. Depending on the ratio, each gear has an output shaft and an input shaft. Gear motors use hydraulic pressure to produce torque. The pressure builds on one side of the motor until it generates enough torque to power a rotating load. This type of motors is not recommended for applications where load reversals occur, as the holding torque will diminish with age and shaft vibration. However, it can be used for precision applications.

Size

The safety factor, or SF, of a gear motor is an important consideration when selecting one for a particular application. It compensates for the stresses placed on the gearing and enables it to run at maximum efficiency. Manufacturers provide tables detailing typical applications, with multiplication factors for duty. A gear motor with a SF of three or more is suitable for difficult applications, while a gearmotor with a SF of one or two is suitable for relatively easy applications.
The global gear motor market is highly fragmented, with numerous small players catering to various end-use industries.

Cost

A gear motor is an electric motor that is paired with a gear train. They are available in AC or DC power systems. Compared to conventional motors, gear reducers can maximize torque while maintaining compact dimensions. But the trade-off is the reduced output shaft speed and overall efficiency. However, when used correctly, a gear motor can produce optimal output and mechanical fit. To understand how a gear motor works, let’s look at two types: right-angle geared motors and inline geared motors. The first two types are usually used in automation equipment and in agricultural and medical applications. The latter type is designed for rugged applications.
In addition to its efficiency, DC gear motors are space-saving and have low energy consumption. They can be used in a number of applications including money counters and printers. Automatic window machines and curtains, glass curtain walls, and banknote vending machines are some of the other major applications of these motors. They can cost up to 10 horsepower, which is a lot for an industrial machine. However, these are not all-out expensive.
Electric gear motors are versatile and widely used. However, they do not work well in applications requiring high shaft speed and torque. Examples of these include conveyor drives, frozen beverage machines, and medical tools. These applications require high shaft speed, so gear motors are not ideal for these applications. However, if noise and other problems are not a concern, a motor-only solution may be the better choice. This way, you can use a single motor for multiple applications.

Maintenance

Geared motors are among the most common equipment used for drive trains. Proper maintenance can prevent damage and maximize their efficiency. A guide to gear motor maintenance is available from WEG. To prevent further damage, follow these maintenance steps:
Regularly check electrical connections. Check for loose connections and torque them to the recommended values. Also, check the contacts and relays to make sure they are not tangled or damaged. Check the environment around the gear motor to prevent dust from clogging the passageway of electric current. A proper maintenance plan will help you identify problems and extend their life. The manual will also tell you about any problems with the gearmotor. However, this is not enough – it is important to check the condition of the gearbox and its parts.
Conduct visual inspection. The purpose of visual inspection is to note any irregularities that may indicate possible problems with the gear motor. A dirty motor may be an indication of a rough environment and a lot of problems. You can also perform a smell test. If you can smell a burned odor coming from the windings, there may be an overheating problem. Overheating can cause the windings to burn and damage.
Reactive maintenance is the most common method of motor maintenance. In this type of maintenance, you only perform repairs if the motor stops working due to a malfunction. Regular inspection is necessary to avoid unexpected motor failures. By using a logbook to document motor operations, you can determine when it is time to replace the gear motor. In contrast to preventive maintenance, reactive maintenance requires no regular tests or services. However, it is recommended to perform inspections every six months.
