Product Description:

The model MKD041B-144-GG1-KN is a synchronous motor designed for high performance industrial automation applications. This motor is manufactured by Bosch Rexroth. It is suitable for use in a range of environments and is typically integrated into automated systems requiring reliable motion control.

The MKD series motor has a maximum speed of 7500 rpm and is rated for a continuous operating torque of 1.4 Nm at 3000 rpm or 1.5 Nm at 4500 rpm. This depends on the cooling method used (natural cooling at 60 K or 100 K overtemperature). It operates with a rated current of 2.8 A at 115 V or 3.0 A at 170 V with rated power outputs of 0.52 kW and 0.88 kW respectively. The motor can handle peak currents up to 34 A that provides flexibility for applications requiring bursts of high torque. Its continuous torque at a standstill is rated at 2.7 Nm or 2.9 Nm. The housing has an IP65 protection rating allowing the motor to function in challenging industrial settings. It is designed to operate within ambient temperatures ranging from 0 to 40 degrees C with storage conditions between - 20 degrees C and + 80 degrees C.

The MKD041B-144-GG1-KN synchronous motor has a rotor inertia of 1.7 x 10^-4 kgm^2 that contributes to its stability during rapid accelerations and decelerations. It also includes a holding brake with a holding torque of 2.2 Nm and operates at 24 V with a current rating of 0.34 A. The motor's insulation class is F that ensures a high resistance to temperature induced wear. The motor's robust design includes a prime black housing coat in accordance with RAL 9005 that enhances its durability and visual appearance.

Fault/Error What It Means Corrective Action
F219 Motor overtemperature shutdown Reduce ambient or cabinet temperature; remove airflow obstructions; allow motor to cool and verify proper load sizing
F221 Motor-temperature sensor defective or disconnected Check PTC/NTC wiring for breaks; megger-test sensor; replace sensor or motor if wiring is intact
F2174 Loss of motor-encoder reference Restore encoder backup power or battery; inspect feedback cable; re-reference the axis after clearing the error
F822 Encoder 1 signal amplitude too small Inspect feedback cable shielding; route encoder leads away from power cables; replace encoder if signal remains weak
F860 Over-current (short in power stage) Check motor-power cable for shorts; test insulation resistance; replace drive/controller if bridge transistors are damaged
F870 +24 V DC control-supply error Verify external 24 V supply voltage and cabling; replace overloaded or failed power supply; inspect E-stop circuit for shorts
F873 Power-supply driver-stage fault Measure driver-stage supply rail; if low, repair or replace drive power section
F878 Velocity-loop error (regulation unstable) Check motor-cable phasing; review velocity-loop parameters; verify commutation offset; replace feedback device if faulty
F879 Velocity limit exceeded (S-0-0091) Reduce commanded torque or speed; lower bipolar velocity limit parameter to a value below rated speed
F208 Motor type has changed (new motor connected) Run C700 basic-load command or press S1 reset; save new motor data set in controller parameters
