maxon motor's newly developed DECV 50/5 is a compact, digital 4-quadrant speed controller for controlling brushless DC motors of up to 250-watt power. Input voltage ranges from 12 - 50 VDC. Speed control means that a low-cost drive solution can be realized using Hall sensor signals without an encoder.
The new DECV 50/5 (Digital EC Controller Voltage regulated) allows 4-quadrant operation for brushless DC motors with Hall sensors using simple settings. The control device is designed for 5 A in continuous operation (up to 10 A intermittently).
There are two set values for regulating speed and current restriction, and the required speed range and speed ramp are pre-selected per DIP switch.
A robustly designed and extremely stable PI speed controller (not suitable as position controller) makes the amplifier ideal for uncomplicated usage. The motor can be constantly monitored for speed and current using the analog monitor outputs.
The internal production of motor link circuit voltage minimizes the current ripple in the motor cables and prevents the motor from overheating, particularly a low-impedance one.
These characteristics make the DECV 50/5 the ideal choice for high-speed motor control and give it a broad range of applications, e.g. power tools (high-speed drills, cutters etc.). No additional motor chokes are necessary for operation.
Assembly is simple thanks to the compact aluminium casing which has a wide range of fastening options. A separable screw terminal makes it easy to change the controller. The controller has protective functions against overcurrent, overvoltage, thermal overload and the short-circuiting of the motor cables
