For applications where variable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide rate range, low heat and maintenance-free operation. Stepper Motors provide high torque and simple low speed operation.
Speed is typically controlled by manual operation on the driver or by an exterior switch, or with an external 0~10 VDC. Acceleration control systems typically use gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations vary to based on space constraints or style of the application.
The drives are powerful and durable and show a concise and lightweight design.
The compact design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. This is achieved through the consistent application of aluminium die casting technology, which ensures a high amount of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested specifically for each order and customer. A sophisticated modular system allows for a great diversity of types and a maximum amount of customization to customer requirements.
In both rotation directions, described end positions are shielded by two position limit switches. This uncomplicated answer does not only simplify the cabling, but also can help you configure the end positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low quickness. The speed specifications for these motors are normal speed and stall-rate torque. These motors use gears, typically assembled as a gearbox, to lessen speed, which makes more torque obtainable. Gearmotors ‘re normally used in applications that require a lot of force to move heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors may also be used as gearmotors … a lot of which are found in automotive applications.
Gearmotors have numerous advantages over other styles of motor/equipment combinations. Perhaps most of all, can simplify style and implementation by eliminating the step of separately developing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is usually that getting the right combination of engine and gearing may prolong design life and allow for maximum power management and use.
Such problems are common when a separate motor and gear reducer are linked together and result in more engineering time and cost along with the potential for misalignment causing bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the use of new specialty materials, coatings and bearings, and in addition improved gear tooth styles that are optimized for noise reduction, increase in power and improved life, all of which allows for improved efficiency in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be mixed and matched as had a need to best fit the application, but in the finish, the complete gearmotor is the driving factor. There are numerous of motors and gearbox types which can be mixed; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with long term irrigation gearbox magnet dc, ac induction, or brushless dc motors.
