This chapter contains information on how to mount a motor on a STOBER gear unit with a motor adapter. The motor adapter type of your gear unit can be found on the nameplate of the gear unit. STOBER recommends using a motor with a shaft without a feather key, since the keyway negatively affects smooth operation.
Permitted tilting torques at the gear unit input If you mount a STOBER gear unit on the machine in a horizontal mounting position, check that the permitted tilting torque is not exceeded on the gear unit input before mounting the corresponding motor. Information on the permitted tilting...
Procedure In order to prevent unfavorable shifting or tilting of the motor shaft, STOBER recommends mounting the motor on the gear unit with the motor shaft pointing down vertically. 1. Position the gear unit (5), if necessary with the aid of lifting gear, so that the motor can be mounted in a vertical position.
Page 17
5 | Installation 9. If necessary, use two suitable attachment points to secure the motor with the lifting gear so that the motor shaft is pointing down vertically. 10. Turn the motor in an axial position to the gear unit so that the nameplates are on the same side, if possible, and can also be read after installation in the machine.

This chapter describes the attachment of a motor with a solid shaft with feather key to a STOBER gear unit with an MQ (for a square motor flange) or MR (for a round motor flange) motor adapter with a curved tooth coupling. Since the assembly steps for the MQ or MR motor adapter are identical, only one motor adapter type is shown in the figures.

The maximum surface temperature occurs in approx. 3 hours, depending on the utilization of the drive, and must not exceed the maximum value of 90 °C in the event of a maximum surrounding temperature. Immediately shutdown the drive if the maximum value is exceeded and contact STOBER Service.
7 | Servicing Servicing Cleaning If the surface of the drive is dirty, heat dissipation through the ambient air is no longer sufficient. As a result, impermissibly high operating temperatures that reduce the lubricating effect of the lubricant and accelerate its aging could occur. This has a negative effect on the service life of the drive.
Servicing Have the necessary servicing work carried out on the drive by the STOBER Service department or by STOBER service partners. Be aware that improper servicing may cause material damage and may void the manufacturer's warranty. Only use replacement parts delivered by STOBER. Specify the type designation and serial number of the drive when...
7 | Servicing Service If you contact STOBER Service, have the following information ready: § Serial number and type designation of the drive according to the nameplate § Type of fault and surrounding circumstances § Presumed cause § If possible, digital photo of the drive or a video recording of the drive in the context of the fault Contact data of parent company in Germany STÖBER Antriebstechnik GmbH + Co.
8 | Removal and disposal Removal and disposal Removal Remove the drive as follows: 1. If the drive had been in operation immediately beforehand, allow it to cool. 2. Disconnect the connection cable and the grounding conductor from the motor. 3.
8 | Removal and disposal Feather key Hollow shaft Set screw Keeper plate Machine shaft Disposal Dispose of the component parts of the gear unit according to applicable national regulations and when doing so, observe the following information: § If possible, separate the gear unit into component parts made of steel/cast iron, aluminum and plastic. §...
