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 because of their wide rate range, low high temperature and maintenance-free procedure. Stepper Motors offer high torque and simple low speed operation.
Speed is typically managed by manual procedure on the driver or by an exterior switch, or with an external 0~10 VDC. Acceleration control systems typically make use of gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations vary 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 manufactured possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is accomplished through the consistent application of 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 each order and customer. A sophisticated modular system allows for a great diversity of types and a optimum degree 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 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 acceleration. The speed specifications for these motors are normal speed and stall-rate torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, making more torque offered. Gearmotors are most often used 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. However, dc motors may also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have numerous advantages over other types of motor/gear combinations. Perhaps most of all, can simplify style and implementation through the elimination of the step of separately designing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors is usually that getting the right combination of motor and gearing can prolong design life and invite for optimum power management and use.
Such problems are common when a separate electric motor and gear reducer are linked together and result in more engineering time and cost along with the potential for misalignment causing bearing failure and ultimately reduced useful life.
Advances in gearmotor technology include the use of new specialty Center-drive gear motor materials, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise reduction, increase in strength and improved life, all of which allows for improved overall performance in smaller deals. More after 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 may be the driving factor. There are many 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.
