Product Description:

The Bosch Rexroth Indramat MAF100D-0250-FQ-S2-HH0-35-H1 is an asynchronous housing motor from the MAF IndraDyn Asynchronous Motors series. It is used in automated production lines that require continuous torque while an internal coolant circuit stabilizes the stator jacket temperature. The motor follows DIN EN 60034-14 vibration guidelines and uses frame size 100 with length code D. It can be installed with flange or foot mounting, and because it comes without a holding brake, motion retention during power loss must be provided by the drive or by a mechanical lock. Its enclosed design also suits machinery where the motor is mounted close to active process equipment.

The motor runs at a rated speed of 2500 rpm and removes heat through liquid cooling. The cooling jacket connects to plant piping through a 1/4-inch threaded port. Rotor position is reported by a single-turn absolute encoder with EnDat2.1 communication, and the encoder electronics operate on 7 to 12 V. The windings use class F insulation for higher thermal tolerance during continuous operation. A turnable terminal box on the B-side houses the power leads so cable direction can be adjusted after installation, and the housing has an IP65 rating to protect the stator cavity from dust and low-pressure water jets.

The motor uses a plain shaft for direct torque transfer to couplings or pulleys. There is no shaft sealing ring at the mechanical end, and the encoder’s optical disk provides 2048 increments for precise speed feedback. The bearing arrangement uses high-speed bearings to support rapid acceleration with winding code 0250 and to handle the related radial loads. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and vibration level A keeps mechanical forces low during operation. The feedback system and bearing arrangement support stable speed control during repeated acceleration and deceleration.
