The motor length is only 285mm (including encoder), and with the B5 flange mounting type, it can be adapted to narrow installation spaces such as CNC machine tool feed axes and robot joints.
The lightweight design (19kg) reduces the inertia at the load end, providing a foundation for high dynamic response of the system.

The bearings use Schaeffler high-precision bearings, filled with long-acting synthetic lubricating grease, reducing maintenance frequency.

2.5 Modular Adaptation and Intelligent Maintenance for Reduced Integration Costs

Adopts a standardized installation interface (M1-type flange), which can directly replace motors of other brands with the same specification without modifying the equipment installation structure.
Supports plug-and-play with Rexroth IndraDrive series drives, automatically reading motor parameters through the DRIVE-CLiQ interface, eliminating the need for manual configuration and shortening the integration cycle.
Built-in intelligent monitoring components can feed back motor temperature, speed, operating status and other data in real time. The drive can realize fault alarm and protection for overload, over-temperature, over-voltage, etc. With the status indicator window, maintenance personnel can quickly locate faults and reduce maintenance costs.

Working Principle

3.1 Command Receiving and Drive Signal Generation

The upper controller (such as CNC, PLC) sends speed, position, or torque commands to the Rexroth IndraDrive drive. The drive reads the inherent motor parameters (such as rated power, number of pole pairs) through the DRIVE-CLiQ interface, and generates three-phase sine wave drive current after processing by the vector control algorithm.
At the same time, the drive receives the motor feedback signal in real time through the encoder interface, laying the foundation for closed-loop control.

3.2 Magnetic Field Interaction and Power Output

The three-phase current output by the drive is applied to the motor stator windings, generating a rotating magnetic field (synchronous speed n=60f/p, where f is the current frequency and p is the number of pole pairs).
The rotor permanent magnets generate a constant magnetic field. The stator rotating magnetic field interacts with the rotor magnetic field to generate electromagnetic torque, driving the rotor to rotate synchronously.
By adjusting the frequency (to regulate speed) and amplitude (to regulate torque) of the drive current, precise control of the motor speed and torque is achieved.
During position control, the drive dynamically adjusts the phase of the rotating magnetic field according to the deviation between the command position and the encoder feedback position, ensuring the rotor accurately reaches the target position.

3.3 Status Feedback and Closed-Loop Regulation

The encoder collects the rotor position and speed signals in real time and transmits them to the drive through differential signals. The drive calculates the deviation between the command and the feedback, and dynamically optimizes the phase and amplitude of the output current to realize closed-loop regulation of speed, position, or torque.
The built-in PTC thermistor monitors the winding temperature in real time. When the temperature exceeds 150℃, it sends an over-temperature signal to the drive, which immediately cuts off the output and alarms to protect the motor from overheating damage.
The intelligent fan automatically adjusts its speed according to the motor temperature (running at low speed below 30℃ and high speed above 60℃), balancing heat dissipation and energy consumption.

3.4 Auxiliary Function Support

The standard self-fan cooling system realizes on-demand heat dissipation through intelligent temperature control, reducing operating noise and energy consumption.
The optional electromagnetic brake device is energized to brake when the motor stops, preventing the rotor from sliding and ensuring positioning accuracy.
The modular interface design supports encoder upgrades (such as replacing with an absolute encoder) and cooling method upgrades (from self-fan cooling to water cooling), improving equipment expandability.

Common Faults and Solutions

4.1 Fault 1: Motor Fails to Start, Drive Reports "Motor Communication Fault"

Possible Causes

Loose or damaged DRIVE-CLiQ cable connection.
Motor parameters not recognized by the drive.
Drive interface fault.
Motor encoder fault.

Solutions

Check the connectors at both ends of the DRIVE-CLiQ cable, re-plug and fasten them, and confirm the cable is not damaged.
Re-execute the "motor identification" process through the IndraWorks engineering software to ensure the drive reads the complete motor parameters.
Replace with a DRIVE-CLiQ cable of the same model for testing to rule out cable faults.
Connect the motor to a normal drive. If the fault is still reported, the motor encoder or communication interface is faulty, and the motor needs to be returned to the factory for repair.

4.2 Fault 2: Decreased Operating Precision, Excessive Position Deviation

Possible Causes

Encoder signal interference.
Excessive coaxiality deviation between the motor and the load.
Unoptimized drive parameters.
Wear of mechanical transmission components (such as lead screw backlash).

Solutions

Check if the encoder cable is a shielded twisted pair, whether the shield layer is single-ended grounded (grounding resistance ≤4Ω), and ensure the distance from the power cable is ≥30cm.
Use a dial indicator to detect the coaxiality between the motor and the load. The radial runout should be ≤0.03mm and the end runout ≤0.02mm. Adjust the installation position if the deviation exceeds the standard.
Optimize the position loop and speed loop parameters (such as increasing the position loop gain) through the drive software.
Check the mechanical transmission components and replace worn parts such as lead screws and couplings.

4.3 Fault 3: Abnormal Noise and Vibration During Operation

Possible Causes

Misalignment between the motor and the load.
Bearing wear or lubrication failure.
Poor dynamic balance of the rotor.
Load jamming.

Solutions

Re-calibrate the coaxiality between the motor and the load to meet the installation standards.
Remove the motor end cover, check if the bearings are worn or the grease is dried up, replace the bearings and add special lubricating grease.
Conduct a dynamic balance test on the motor rotor. The unbalance should be ≤G1.0 class (ISO 1940-1). If the deviation exceeds the standard, return the rotor to the factory for correction.
Disconnect the connection between the motor and the load, manually rotate the load shaft, and troubleshoot load jamming faults (such as reducer jamming, poor guide rail lubrication).

4.4 Fault 4: Drive Reports "Motor Over-Temperature" Fault

Possible Causes

Long-term overload operation of the motor.
Faulty cooling fan or blocked air duct.
Excessively high ambient temperature.
PTC thermistor fault.

Solutions

Monitor the real-time motor torque through the drive software. If it exceeds the rated value for a long time, evaluate the load matching and replace with a higher-power motor if necessary.
Check if the cooling fan is running, clean the dust on the motor surface and air duct, and replace the fan if it is faulty.
When the ambient temperature exceeds 45℃, install an additional cooling fan or water-cooling kit, and implement derating at the same time.
Measure the resistance value of the PTC thermistor. It should be approximately 1kΩ at room temperature and 10kΩ at 150℃. Replace the thermistor if the resistance is abnormal.

4.5 Fault 5: Encoder Fault Alarm, Closed-Loop Control Failure

Possible Causes

Loose or broken encoder cable.
Internal encoder damage (code disc contamination/wear).
Drive encoder interface fault.
Unstable power supply voltage.

Solutions

Re-fasten the encoder cable connectors, check the cable integrity, and replace the damaged cable.
Remove the encoder end cover, clean the oil and dust on the code disc surface. Replace the encoder if the code disc is worn.
Connect a normal encoder to the faulty drive. If the alarm is still triggered, the drive interface is faulty and needs to be repaired.
Measure the encoder power supply voltage (DC 5V±0.1V). If the voltage is unstable, troubleshoot the drive power supply circuit.
