For applications where variable speeds are necessary, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide speed range, low high temperature and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically controlled by manual procedure on the driver or by an external switch, or with an external 0~10 VDC. Acceleration control systems typically use gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid based 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 show a compact and lightweight design.
The compact design is made possible through the combination of a spur/worm gear drive with motors optimized for performance. That is attained through the consistent application of aluminum die casting technology, which guarantees a high amount of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested particularly for each order and customer. A sophisticated modular system permits a great diversity of types and a optimum amount of customization to client requirements.
In both rotation directions, described end positions are guarded by two position limit switches. This uncomplicated answer does not only simplify the cabling, but also can help you configure the end positions quickly and easily. 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 quickness. The speed specifications for these motors are normal speed and stall-swiftness torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque obtainable. Gearmotors ‘re normally utilized 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. 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 of all, can simplify style and implementation by eliminating the step of separately creating and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is certainly that Center-drive gear motor having the right combination of electric motor and gearing can prolong design life and invite for the best power management and use.
Such problems are common when a separate motor and gear reducer are connected together and lead to more engineering time and cost and also the potential for misalignment causing bearing failure and ultimately reduced useful life.
Advances in gearmotor technology include the use of new specialty materials, coatings and bearings, and also improved gear tooth styles that are optimized for noise reduction, increase in strength and improved life, which allows for improved overall performance in smaller deals. More following the jump.
Conceptually, motors and gearboxes could be blended and matched as needed to best fit the application, 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, the right angle wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
