Thousands of miles of underground EC Motors pipes are responsible for handling important tasks. They have to operate reliably. Internal inspection and maintenance has so far only been possible
where pipe diameters ec motors are large. Relatively small
sewers do not offer enough space for human beings, and whenever they were damaged the only solution was to expose
the affected pipe sections. An expensive undertaking. However, new developments in the field of electronics and motion control
engineering now make it possible to inspect and ec motors perform maintenance
in small sewers - internally. Since in
the sewage sector all tools have to meet very high standards of reliability and performance, the drives on such sewer robots ec motors have to
be extremely robust. Modern bell-type armature DC motors satisfy the exacting requirements for use inside of the pipe ec motors system.

The large and extensive sewage networks operated by local authorities and companies, which are often quite old, require regular maintenance. In an increasing number of cases there is minor and major damage to be repaired. For such work on the pipe system PROKASRO, a sewer robot specialist, developed an extensive range of tools and equipment. From an autonomous service vehicle (fig. 1) with auxiliary equipment such as a generator, compressor, water tank, and electronic control the robot is steered using a cable remote control and a monitor.
Trailing cable
Sewer robots have various sizes, tooling, and other specific features depending on the type of service (fig. 2). What they all have in common is supply and control via a supply cable. The cable is comprised of 32 electric wires, four compressed air hoses and four water hoses. The robot drags this trailing "umbilical cord", which is 39 mm thick, behind it through the sewer. The standard length is 120 m but it is also possible to reach lengths of up to 200 m. At that length and with the amount of dirt that always occurs in the sewer a powerful drive is absolutely vital for smooth operation.
The problem was solved by using miniature DC motors incorporating a coreless rotor - made by FAULHABER.
For example, one version of the robot is equipped with nine motors of this type in order to allow flexible operation under ground. The drive used consists of four axes each comprised of one Series 3557...CR motor. The motor is coupled to a gearhead in order to be able to ensure optimal adjustment of speed and traction.
The advantage of this solution is that the same robot can work in large pipes with large wheels; appropriately stepped-down gears reduce the rotary speed in proportion to wheel size. Velocity and traction are thus kept independent of wheel diameter; the operator at the service vehicle can work as accustomed. A
