The Pipestoppers Division at Huntingdon Fusion Techniques HFT® has designed and manufactured a range of mechanical and inflatable Pipestoppers and Plugs for a variety of applications.
Brother Gearmotors has introduced IPMax, a line of lightweight, compact interior permanent magnet (IPM) gearmotors. The series of IPMax maximum performance gearmotors incorporate magnets embedded within the rotor as opposed to on the surface. No copper losses are experienced in the rotor and considerably less copper losses occur in stator winding. The gearmotors can operate fanless up to 1 hp and do not require encoders for sensor control. When stopped, a servo lock feature holds the motor in position.
