Product Description:

Bosch Rexroth Indramat’s MAF100B-0250-FQ-S0-AG0-05-R1 belongs to the MAF IndraDyn Asynchronous Motors series and is categorized as a liquid-cooled asynchronous housing motor for industrial automation. The unit couples directly to Rexroth drive controllers and supplies rotary motion where compact size and continuous thermal stability are required, such as in printing lines or metal-forming equipment. Its frame size 100 and frame length B give a moderate footprint, while the A-side power connector simplifies routing inside sealed cabinets.

The motor removes heat through an internal channel that circulates coolant, and this method is listed as liquid cooling. Coolant enters the tubing through a port machined with a 1/4 inch connection thread, allowing standard fittings to clamp onto the housing. During operation, the enclosure resists dust and water jets up to the IP65 rating, so external washdowns do not compromise winding life. The rotor reaches a rated speed of 2500 min⁻¹, matching the 0250 winding code and enabling direct coupling to gear stages without overspeeding the stator. Mechanical integration is handled by flange mounting, which centers the motor on driven machinery and absorbs radial forces evenly. Electronics and lubricant seals remain within specification when the ambient air stays between 0 – 40 °C, preventing condensation or insulation degradation.

The stator windings are impregnated to insulation class F, allowing conductor temperatures up to 155 °C before thermal aging accelerates. Torque is delivered through a plain shaft, and a shaft sealing ring blocks splash ingress so that external gearboxes stay free of coolant. Dynamic balance meets vibration level A, and the overall design complies with DIN EN 60034-14, ensuring the motor’s vibration limits correspond with common industrial machinery tolerances. A holding brake is intentionally omitted, so axial locking must be provided by the application’s drivetrain or by the drive controller’s regenerative torque. This arrangement is commonly used when the driven mechanism provides its own holding force at standstill.
