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 because of their wide acceleration range, low high temperature and maintenance-free procedure. Stepper Motors offer high torque and even 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. Quickness control systems typically utilize gearheads to increase result torque. Gear types range between spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations differ to depending on space constraints or style 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 guarantees a high amount of rigidity for the apparatus and motor housing at the same time.
Each drive is produced and tested specifically for each order and customer. A advanced modular system allows for a great diversity of types and a maximum degree of customization to client requirements.
In both rotation directions, described end positions are protected by two position limit switches. This uncomplicated remedy does not only simplify the cabling, but also makes it possible to configure the finish positions efficiently. The high shut-off accuracy of the limit switches guarantees safe operation moving forwards and backwards.
A gearmotor delivers high torque at low horsepower or low acceleration. The speed specs for these motors are normal speed and Center-drive gear motor stall-speed torque. These motors use gears, typically assembled as a gearbox, to reduce speed, which makes more torque obtainable. Gearmotors ‘re normally utilized in applications that need a whole lot of force to go heavy objects.
By and large, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be utilized as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the step of separately developing and integrating the motors with the gears, thus reducing engineering costs.
Another advantage of gearmotors is that getting the right combination of electric motor and gearing can prolong design life and allow for optimum power management and use.
Such problems are normal when a separate electric 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 ultimately reduced useful life.
Advancements in gearmotor technology include the usage 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, all of which allows for improved functionality in smaller deals. More following the jump.
Conceptually, motors and gearboxes could be mixed and matched as needed to greatest fit the application form, but in the finish, the complete gearmotor is the driving factor. There are a number of motors and gearbox types which can be mixed; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
