For applications where adjustable speeds are necessary, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide swiftness range, low high temperature and maintenance-free procedure. Stepper Motors provide high torque and clean low speed operation.
Speed is typically controlled by manual procedure on the driver or by an external switch, or with an exterior 0~10 VDC. Velocity control systems typically use gearheads to increase output 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 style of the application.
The drives are powerful and durable and feature a concise and lightweight design.
The compact design is made possible through the combination of a spur/worm gear drive with motors optimized for performance. This is accomplished through the consistent application of light weight aluminum die casting technology, which guarantees a high degree of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested specifically for every order and customer. A sophisticated modular system permits a great diversity of types and a maximum degree of customization to customer requirements.
In both rotation directions, described end positions are secured by two position limit switches. This uncomplicated alternative does not just simplify the cabling, but also can help you configure the finish positions efficiently. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A Center-drive gear motor gearmotor delivers high torque at low horsepower or low swiftness. The speed specs for these motors are regular speed and stall-swiftness torque. These motors use gears, typically assembled as a gearbox, to lessen speed, which makes more torque available. Gearmotors ‘re normally utilized in applications that need a whole lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be used as gearmotors … a lot of which are found in automotive applications.
Gearmotors have several advantages over other styles of motor/gear combinations. Perhaps most importantly, can simplify design and implementation by eliminating the step of separately designing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors can be that having the right combination of motor and gearing can prolong design life and allow for ideal power management and use.
Such problems are normal when a separate motor and gear reducer are connected together and result in more engineering time and cost along with the potential for misalignment causing bearing failure and eventually reduced useful life.
Advances in gearmotor technology include the usage of new specialty materials, coatings and bearings, and in addition improved gear tooth designs that are optimized for sound reduction, increase in strength and improved life, which allows for improved performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be blended and matched as had a need to greatest fit the application form, but in the finish, the complete gearmotor may be the driving factor. There are numerous of motors and gearbox types which can be combined; for example, the right angle wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
