The separately ventilated three-phase motors 1LG4 of shaft height 315 are especially suitable for use as hoist motors in medium-output drives. The axially mounted external fan means that the motors can operate for long periods with rated torque at low speeds, an operating characteristic required, for example, for the hoisting gear of trestle or assembly cranes.

Encoder mounting

The following encoders can be mounted – between the motor NDE and the external fan – (HOG 10 DN 1024 I encoders are installed on cranes):

  • HOG 10 D........
  • HOG 10 D...... with centrifugal switch FSL
  • HOG 10 D...... with centrifugal switch ESL (on request).

The connections of the encoder and centrifugal switch (if applicable) are taken to an auxiliary terminal box. As a result, the fan unit does not need to be disassembled when the encoder cables are connected on the system.

The table below shows an overview of the available motor outputs.

Технические данные

The maximum permissible field‑weakening speed is 2600 rpm for all the variants listed above.

The following rated voltages are available:

  • 400 V 3 AC
  • 460 V 3 AC
  • 500 V 3 AC
  • 690 V 3 AC (special insulation!)

The standard version of the external fan motor is designed for

50 Hz 3 AC 220 – 240 VΔ/380 – 420 VY, 2.0/1.15 A

60 Hz 3 AC 440 – 480 VY, 1.05 A

Other rated voltages can be ordered with order code Y81 and plain text.

We recommend that the external fan motor is ordered with a standstill heater for outdoor installations. Cables for the external fan motors must always enter from below. The fan cowl can be turned accordingly.
The motors are available in types of construction IM B3 and IM B35.

The electrical data of the motors for intermittent duty S3 plus the relevant planning data can be found in the selection and ordering data.
The special models normally required for cranes are the only options listed under "Article number supplements and special versions". For further options, see Catalog D 81.1.

The basic version of the 1LG4 motor without an external fan is described in Catalog D 81.1.
