Motors & Drives Information

Motor speed controller, 200XLV, drives brushed motors, gear-motors, low-inductance printed motors, and linear actuators rated up to 100 W. Suited for low-power applications that rely on unregulated dc or battery supply up to 48 V, 4-quadrant drive measures 82 x 40 x 50 mm and can motor and brake in both directions of rotation. It produces linear, noise free output and features manually adjustable IR drop compensation and speed ramping function.

Arundel, July 2005. Sprint Electric introduces the 200XLV, a miniature, fast response DC motor speed controller for driving brushed DC motors, gear-motors, low inductance printed motors and linear actuators rated up to 100W. The 200XLV is ideal for low power applications such as robotic control and antenna or security camera drives that rely on an unregulated DC or battery supply up to 48V. The unit operates from a single polarity supply and can accept a wide range of supply voltage. Despite measuring just 40mm wide, 82mm high and 50mm deep, the 200XLV is a genuine four quadrant drive that can motor and brake in both directions of rotation to offer outstanding control of motor speed and torque.

In low cost installations, where the use of a tacho generator would not be cost effective, speed regulation is achieved using armature voltage feedback. Speed droop under load can be reduced by the manually adjustable IR drop compensation. Offering high bandwidth and a superbly linear, noise free output, the 200XLV is ideal for control of linear actuators. Here the unit can be used with three term PID control, tacho input and position feedback for accurate speed and position control. A speed ramping function may also be added to provide a quicker response to sudden demand changes, while the drive's set point ramp facility can be used to limit slew rates for applications where a fast response is not required. The 200XLV can be used to control either motor speed or torque, and with internal precision references it provides ultra stable operation.
