Safety information
2.6 Interference immunity
2.7 Influence on the line power supply through a strongly irregular torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a nonsinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
2.8 Interference voltages when operating the converter
WARNING
Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on
the converter (manufacturer, type, interference suppression measures undertaken). On
machines with integrated sensors (e.g. PTC thermistors), interference voltages caused by
the converter may occur on the sensor lead. This can cause faults which can result in eventual
or immediate death, serious injury or material damage.
● Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must put appropriate EMC measures in place.

Efficiency requirement
According to EU Regulation (EC) No. 640/2009, the IE3 efficiency requirement for low-voltage
motors with a power of 7.5 kW to 375 kW for line operation has been in force since January
01, 2015.

Rotors
Cooling
From January 1, 2017, the IE3 efficiency requirement for motors with a power of 0.75 kW to
375 kW applies for line operation.
Efficiency IE2 still applies for motors that are operated from a converter.
Please note the applicable country-specific rules and regulations.
The rotor assembly is pressed onto the shaft together with the cage winding. The drive end of
the shaft usually has a cylindrical shaft end. Dependent on the design, a second shaft end
may be located at the non-drive end.
The cooling system is designed as a closed, internal cooling circuit. The heat lost from the
machine is dissipated partially via heat conduction and partially via the cooling air at the cooling
water flowing through the cooling pipes. A shaft-mounted fan ensures circulation of the cooling
air.

Roller-contact bearings
The machines are equipped with different types of rolling-contact bearings depending on the
version and the operating conditions described in the order. The different types are listed on
the lubricant plate of the machine. In converter operation an insulated bearing is usually
installed on the non-drive end. The following roller-contact bearing variants are available:
Table 3-3 Rolling-contact bearing variants
Version Rolling-contact bearing
Horizontal type of construc‐
tion, coupling output
Vertical type of construc‐
tion, coupling operation
● Drive end: Deep-groove ball bearing as a fixed bearing,
● Non-drive end: Deep-groove ball bearing as a floating bearing with
axial compression springs
● Drive end: Pairing of angular-contact ball bearing / deep-groove ball
bearing as a fixed bearing
● Non-drive end: Deep-groove ball bearing as a floating bearing with
axial compression springs
Rolling-contact bearing design for "Increased degree of protection" (option)
Improved sealing of the bearing units to prevent dust and water from getting in can be achieved
by positioning a grease chamber ahead of the actual bearing unit. Although the same grease
is used in both cases for reasons of convenience, a distinction is made here between
"lubricating grease" and "sealing grease" because of their different functions.
Layout
The spent lubricating grease collects in the space between the bearing housing and the outer
bearing cap. The latter also forms the sealing grease chamber with the labyrinth sealing ring
(optional). The second lubricating nipple containing the grease duct for pressing in the sealing
grease is also located in the outer bearing cap. The chamber is sealed off from the space
where the lubricating grease collects by a V-ring or a V-ring and felt ring combination which
prevents the sealing grease in the chamber from penetrating into the lubricating grease
collecting space. During operation, the sealing grease in the chamber slowly runs out via the
labyrinth and seals it, additionally removing dust from inside and around the outside of the
labyrinth ring.
Terminal box
The terminal box is positioned on the side of the machine. It is fixed to the machine and cannot
be exchanged.
Supplementary devices
Depending on the order, various supplementary devices can be installed or mounted. These
include sensors for bearing temperature monitoring or winding monitoring, for example.

WARNING
Excessively high speeds
Excessive rotational speed can lead to serious damage to the machine. This can result in
death, serious injury, or material damage.
● Avoid operation above the permissible speed by using the appropriate control function.
● Observe the speeds stamped on the rating plate.
4.10 Phase synchronization during supply system switching
NOTICE
Supply system switching
Damage to the machine may be caused when switching to another supply system with
different phasing.
● The phasing must be synchronized during switching. Use appropriate means to
synchronize the phasing.
4.11 Voltage and frequency fluctuations during line operation
If nothing else is stamped on the nameplate, then the permissible voltage fluctuation is ±5 %
and the permissible frequency fluctuation is ±2 %, corresponding to range A in
IEC / EN 60034‑1. Permissible fluctuations that go beyond this are specified on the nameplate,
e.g. voltage fluctuation of ±10 % corresponding to range B in IEC / EN 60034‑1.
The following applies: Under practical operating conditions a machine may sometimes have
to be operated outside the limits of Range A. Exceptions of this sort should be limited with
regard to the values that arise, how often and for how long they occur. Where possible and
within a reasonable time take corrective actions such as reducing the power. Such actions can
avoid thermal ageing leading to a reduction in the service life of the machine.
NOTICE
Overheating of the winding
Exceeding the permissible tolerances for voltage and frequency can lead to an impermissibly
high temperature rise in the windings and thus cause long-term damage to the machine.
