Brake Motors
LHP Brake Motors are designed for reliable and safe stopping in applications such as packaging lines. They use fail-safe electromagnetic brakes mounted on the rear side of the motor. The brakes operate on DC supply and engage automatically when the power is switched off. A built-in rectifier in the terminal box converts AC power to DC for smooth brake operation. These motors are available from range 0.09 kW to 90 kW with protection class IP55, IP56, IP57, IP66 and IP67 as optional.
Roller Table Motors
LHP Roller Table Motors are specially designed for conveyors used to move steel billets through roller mills in steel plants. These motors comply with IPSS No. 1-03-007-14 and are available up to 500KW and 450 frame size in 4, 6, and 8 poles. They can operate reliably in extreme ambient temperatures from -35°C to +70°C. Options include online greasing, PTC thermistors, RTD/BTD sensors, encoders, and electromagnetic brakes.
Encoder Motors
These motors feature an inbuilt incremental encoder that provides real-time feedback for accurate and reliable motor control. Encoders are available for motors up to 315 kW with a robust bearing and safety-lock design. Large bearings and solid construction ensure high stability against vibrations and installation errors. The encoder is integrated under the fan cowl, making it suitable for harsh outdoor applications.
