For applications where adjustable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide speed range, low temperature and maintenance-free procedure. Stepper Motors offer high torque and clean low speed operation.
Speed is typically controlled by manual procedure on the driver or by an exterior change, or with an exterior 0~10 VDC. Swiftness control systems typically use gearheads to increase result torque. Gear types range between spur, worm or Center-drive gear motor helical / hypoid depending on torque needs and budgets.
Mounting configurations differ to based on space constraints or style of the application.
The drives are powerful and durable and show a compact 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 attained through the constant application of light weight aluminum die casting technology, which ensures a high amount of rigidity for the apparatus and motor housing simultaneously.
Each drive is produced and tested particularly for every order and customer. A advanced modular system permits a great diversity of types and a maximum degree of customization to consumer requirements.
In both rotation directions, defined end positions are secured by two position limit switches. This uncomplicated remedy 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 ensures safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low speed. The speed specifications for these motors are normal speed and stall-velocity torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque available. Gearmotors are most often used in applications that require a whole lot of force to move heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors can also be utilized as gearmotors … a lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify design and implementation by eliminating the stage of separately designing and integrating the motors with the gears, therefore reducing engineering costs.
Another benefit of gearmotors is definitely that getting the right combination of electric motor and gearing can prolong design life and invite for the best possible power management and use.
Such problems are common when a separate engine and gear reducer are connected together and result in 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 components, 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 performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes could be combined and matched as had a need to best 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 mixed; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with permanent magnet dc, ac induction, or brushless dc motors.
