Low-cost speed-and-direction controller for DC motors
Rotalink is launching a low-cost speed-and-direction controller for DC motors up to 1.5 A that features pulse width modulation (PWM) for high-quality speed control with an on-board potentiometer for smooth and precise adjustment. The board-mounted unit, measuring just 63mm x 46mm, has a wide user supply range from 7-24V DC with the single-turn potentiometer set at 50 per cent for zero speed. The unit is aimed at OEMs and users wishing to include a simple yet practical speed-and-direction control for Rotalink motors with a single source supply, and without the unnecessary burden of their own design and manufacture.
The new speed-and-direction controller may be used across Rotalink's extensive range of brushed DC motors, which includes standard ferrite and high-performance rare earth magnet systems, as well as heavy-case designs. The controller complements Rotalink's existing portfolio brushed and brushless DC motors, as well as AC motors with the company's own innovative gearbox, motor feedback and motion controls. Rotalink provides competitive miniature power transmission units rated at up to 28Nm output torque for rotary motion and to more than 50N force for linear motion.
Rotalink's full range includes a wide choice of planetary and spur gearboxes that feature standard or enhanced polymer gears on sintered or ball bearings. Rotalink manufactures ovoid-style gearboxes with extremely high torque outputs due to a combination of spur gears with planetary stages and ultra-polymer materials technology.
In addition, Rotalink manufactures a range of incremental and absolute feedback devices, as well as motion controls for DC motors. The Red Drive controller is available for brushed and brushless motors and features easy-to-use drag-and-drop flow chart programming for motion control and combined TTL logic I/O.
