For applications where adjustable speeds are essential, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide swiftness range, low high temperature and maintenance-free procedure. Stepper Motors offer high torque and soft low speed operation.
Speed is typically controlled by manual procedure on the driver or by an external change, or with an exterior 0~10 VDC. Speed control systems typically utilize gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to based on space constraints or design 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. That is accomplished through the constant 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 particularly for every order and customer. A advanced modular system permits an excellent diversity of types and a optimum degree of customization to consumer requirements.
In both rotation directions, described end positions are safeguarded by two position limit switches. This uncomplicated remedy does not just simplify the cabling, but also makes it possible to configure the end positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation moving forwards and backwards.
A gearmotor provides high torque at low horsepower or low quickness. The speed specs for these motors are regular speed and stall-acceleration torque. These motors make use of gears, typically assembled as a gearbox, to Center-drive gear motor lessen speed, which makes more torque offered. Gearmotors are most often used in applications that need a lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors may also be used as gearmotors … a lot of which are used in automotive applications.
Gearmotors have numerous advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify style and implementation by eliminating the stage of separately creating and integrating the motors with the gears, thus reducing engineering costs.
Another advantage of gearmotors is usually that getting the right combination of motor and gearing may prolong design life and allow for ideal power management and use.
Such problems are normal when a separate engine and gear reducer are connected together and lead to more engineering time and cost along with the potential for misalignment leading to bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the utilization of new specialty materials, coatings and bearings, and also improved gear tooth styles that are optimized for sound reduction, increase in power and improved life, which allows for improved efficiency in smaller deals. More after the jump.
Conceptually, motors and gearboxes could be blended and matched as needed to best fit the application form, but in the end, the complete gearmotor is the driving factor. There are many of motors and gearbox types that can be mixed; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
