Choosing combination of gear motors

The combination of gear motor to be chosen depends on the power you actually need to run you machine. If the gear motor can supply the required power then it is fine to choose. Here power means the typical speed and torque operating for the system. Usually, choosing the smallest and lightest is better, which you can also find at lower cost. But, make sure that you keep the constraint of voltage supply in your area in mind, so that your motor can run on that voltage and consume electric current in moderate amount.

Motors efficiently convert electric power into mechanical power at higher speed. Conversely, gearboxes have lower efficiency having larger gear ratios than gearboxes with smaller gear ratios. So, efficiency should be your concern until and unless it is a serious issue for you. Once the motor has been chosen, it is times to select gearbox for the motor. Motor with gearbox combines speed with torque, both in maximum amount. Ensure that the specification of gearbox output shaft maximum torque is in adequate amount. 

Ideally, motor should not be run continuously for hours as there are chances that the motor will overheated. It is better to stall periodically and then use again. The dependency of allowable continuous process area of the speed torque is on thermal characteristics of gear motors. But practically no one wants nonstop operation at less than ¼th or ½ of the maximum motor’s speed. If speed is really your concern, choose larger motor for the required specification.

What are Industrial Gear Motor Units?

Industrial gear motor units are often used where high powered and heavy duty performance is needed. The units are available as stand alone machines or integrated systems and are perfect for use where other machinery cannot stand up to the difficult conditions of high torque demand and long term reliability. The integrated systems come complete with brakes, frames and other components for a fully incorporated drive system.

Industrial gear motor units can be used for a wide variety of demanding applications across industries as varied as food processing and mining. Some common features of the units are a durable gear casing, efficient and effective cooling systems to prevent overheating and breakdown, universal mounting and a high level of customisability and flexibility to ensure the gear motor unit works well with each different application.

Some individual industrial motor unit models are developed for specific applications and processes across all industries. One example can be seen in the products developed for providing power to overhead trolley systems. These industrial drive units provide power, speed and control for both lightweight and heavy duty systems.

Specially designed industrial power units offer benefits previously unheard of in industrial processes. These advantages include higher working loads in all areas of the industrial process, energy efficiency, high accuracy and precise control over speeds as well as more complete automation.

All of these benefits complement the heavy duty capabilities of industrial gear motor units, making them suitable for complex and demanding applications such as mining conveyors, crushers, agitators and shipping cranes.
