MDD025A-N-100-N2G-040PE1
The MDD025A-N-100-N2G-040PE1 is a compact synchronous motor built by Bosch Rexroth Indramat for use in digital drive controllers within the MDD Synchronous Motors series. As a servo element, it converts commanded current from the drive into precise mechanical rotation. This allows machine axes or spindles to follow programmed motion profiles in industrial automation lines, pick-and-place heads, or light gantry systems where high speed, low inertia, and accurate response are required during repeated motion cycles. Its compact format is suited to installations where axis space is limited but precise servo response is still necessary.
This model delivers a continuous stall torque of 0.33 Nm, which is the steady holding or low-speed driving capability without overheating. When accelerated to its nominal speed of 10000 rpm, thermal equilibrium is maintained as long as load torque does not exceed the continuous rating. For brief positioning tasks or power-off holding, the integrated blocking brake supplies up to 1.0 Nm of static torque. Mechanical alignment is simplified by a centering diameter of 40 mm, while electrical and feedback leads exit to the machine's left side. A connecting cable with a coupling unit links the motor to the drive and supports replacement without disconnecting every individual conductor.
Rotor position is reported through resolver feedback, giving analog sine-cosine signals that remain reliable at very high speed. This feedback allows the drive to maintain stable commutation and consistent speed control during fast direction changes. The motor uses a keyway shaft to transmit torque to pulleys or couplings with positive mechanical locking. It also uses a shaft seal to limit lubricant escape and airborne particle ingress. The frame follows size code 025, which keeps the housing compact and helps reduce moving mass on small axes.
