For applications where variable speeds are essential, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option because of their wide rate range, low heat and maintenance-free procedure. Stepper Motors offer high torque and easy low speed operation.
Speed is typically managed by manual procedure on the driver or by an external switch, or with an external 0~10 VDC. Speed control systems typically make use of gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to depending on space constraints or design of the application.
The drives are powerful and durable and feature a compact and lightweight design.
The compact design is made possible through the mixture of a spur/worm gear drive with motors optimized for performance. That is attained through the constant application of light weight aluminum die casting technology, which ensures a high Center-drive gear motor amount of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested specifically for every order and customer. A advanced modular system allows for an excellent diversity of types and a maximum amount of customization to customer requirements.
In both rotation directions, described end positions are secured by two position limit switches. This uncomplicated solution does not only simplify the cabling, but also makes it possible to configure the finish positions efficiently. The high shut-off precision of the limit switches ensures safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low velocity. The speed specifications for these motors are normal speed and stall-acceleration torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque offered. Gearmotors ‘re normally used in applications that require a lot of force to go heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have numerous advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the step of separately designing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors is usually that having the right combination of electric motor and gearing may prolong design life and allow for the best possible power management and use.
Such problems are common when a separate motor and gear reducer are linked together and lead to more engineering time and cost and also the potential for misalignment leading to bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the use of new specialty materials, coatings and bearings, and also improved gear tooth designs that are optimized for sound reduction, increase in power and improved life, all of which allows for improved efficiency in smaller packages. More following the jump.
Conceptually, motors and gearboxes can be blended and matched as had a need to best fit the application, but in the end, the complete gearmotor may be 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 magnet dc, ac induction, or brushless dc motors.
