Maxon Motor announces details of new servo-amplifier range for 10 to 500 Watt DC motors.
It takes its signals directly from the drive unit's internal Hall sensors, which means there is no need for the extra expense and complication of an encoder.
Operation couldn't be simpler, thanks to its convenient settings.
There are two set values for speed regulation and current restriction - the required speed range and speed ramp being preselected by the flick of a DIP switch.

Robot arm aims to reach the unreachable
A novel snake arm robot developed by OC Robotics uses as many as 60 miniature motors to provide freedom of motion.
Specifically configured for control of speed rather than position, the robustly designed and extremely stable PI speed controller functions effectively, and with the minimum of fuss.
For flexibility, a wide input voltage range is offered - from 12 to 50V DC.
The device is designed to handle a 5A current in continuous operation and up to 10A intermittently to allow for overloading.
Motor speed and current can be constantly monitored using easy-to-read analogue outputs.
There is no need to add auxiliary devices such as chokes to protect against overheating of the motor.
Instead this is achieved through internal control of the link circuit voltage, which reduces current ripple.
This is particularly welcome when it comes to low-impedance drive units.
Furthermore, the controller has inbuilt protection against excess current and voltage, thermal overload and short-circuiting of the motor cables.
Assembly is very straightforward thanks to the compact aluminium casing, which has a wide range of mounting options.
A detachable screw terminal block allows quick replacement, while the unit's compact sise - just 95 x 85 x 24mm - means it will fit neatly into any system.
With all these advantages, the DECV 50/5 is the ideal choice for high-speed motor control in a broad range of applications.
It is particularly well suited to use with power tools such as high-speed drills (bone drills, for example), cutters and pumps - in fact any machine whose speed needs to be maintained at a rapid, constant, accurate level over a long period.
"Our aim is to provide an appropriate range of 4-Q and 1-Q controllers to match designers' varying applications and budgets", says Keith Ellenden, CEO of Maxon Motor UK.
"The DECV 50/5 offers a user-friendly, low-cost solution that will answer many needs".
"The current Maxon catalogue - free on request - gives comprehensive data and guidance to help ensure the optimum choice of controller, and of course our specialist sales engineers are always available to advise further". Request a free brochure from Maxon Motor UK ...
