Circuit breaker and protective equipment. Circuit breaker and protective equipment EMC measures Brake motors Encoder connection Positive temperature coefficient thermistor The designated use of SEW-EURODRIVE asynchronous servomotors is as components for installation in machinery and systems. The designer of the machine or system is responsible for complying with the EMC Directive //EEC. Please refer to the publication "Drive Engineering - Practical Implementation, Electromagnetic Compatibility (EMC) in Drive Engineering" for detailed information about this topic. Install the brake cables of brake motors separately from the other power cables, maintaining a distance of at least mm. Joint installation is only permitted if either the brake cable or the power cable is shielded. Please observe the following instructions when connecting an encoder: Use a shielded cable with twisted pair conductors only. Connect the shield to the PE potential on both ends over a large surface area. Route signal cables separately from power cables or brake cables (min. distance mm). Install the connecting lead of the positive temperature coefficient (PTC) thermistor TF separately from other power cables, maintaining a distance of at least mm. Collective installation is only permitted if either the TF cable or the power cable is shielded. GSE
Thermal characteristics. Thermal characteristics Power reduction The thermally permitted torque of a motor depends on the ambient temperature and the installation altitude. The rated torque given on the nameplate applies to a maximum ambient temperature of C and a maximum altitude of m above sea level. The torque must be reduced according to the following formula in the case of higher ambient temperatures or altitudes: M Nred = M N f T f H M N M Nred f H f T = rated torque = reduced rated torque = factor for the installation altitude above sea level = factor for the ambient temperature Refer to the following diagrams for factors f T and f H : f T.... f H....

Motor options / equipment. Disc brake BM(G) General information On request, SEW motors and gearmotors can be supplied with an integrated mechanical brake. The SEW brake is a DC-operated electromagnetic disc brake that is released electrically and applied using spring force. The brake is applied in case of a power failure. This means it complies with fundamental safety requirements. The SEW brake can also be released mechanically if equipped with manual brake release. For this purpose, either a hand lever or a setscrew is supplied with the brake. The hand lever springs back automatically and the setscrew is lockable. The brake is activated by a brake control system accommodated either in the wiring space of the motor or in the control cabinet. A significant advantage of SEW brakes is their very short length. The brake bearing end shield is a part of both the motor and the brake. The integrated construction of the SEW brake motor permits particularly compact and sturdy solutions. Basic structure The illustration below shows the basic structure of the SEW brake. Figure : Basic structure of the SEW brake axx Brake disc Working air gap Brake coil body Brake bearing end shield Pressure plate Motor shaft Carrier Brake spring Electromagnetic force Spring force Brake coil Short response times A particular feature of the SEW brake is its patented two coil system. This system comprises the accelerator coil BS and the coil section TS. The special SEW brake control system ensures that the accelerator coil is switched on with a high current inrush when the brake is released, after which the coil section is switched on. The result is a particularly short response time when releasing the brake. The brake disk moves clear very swiftly and the motor starts up with hardly any brake friction. GSE
Motor options / equipment Overview This principle of the two coil system also reduces self-induction so that the brake is applied more rapidly. The result is a reduced braking distance. The SEW brake can be cut off in the DC and AC circuits to achieve particularly short response times when applying the brake, for example for hoists. The asynchronous servo brake motors are equipped with the following SEW brake types: Brake type For motor Description BMG CT...CVS Double-disc, spring-loaded brake BM CVM...CV Double-disc, spring-loaded brake Technical data Brake type For motor size The following table lists the technical data of SEW brakes.

All SEW brake control systems are protected against overvoltage by varistors as standard. For more information, refer to the "Brakes and Accessores" manual. The brake control systems are either installed directly on the motor in the wiring space or in the control cabinet. As standard, CT/CV...BM(G) servomotors are supplied with installed brake system BGE for AC connection or an installed control unit BSG for DC V connection. The motors are then completely ready for connection.

Motor options / equipment Cross section of the brake cable Note Select the cross section of the brake cables according to the currents in your application. Bear in mind the inrush current of the brake when selecting the cross section. The voltage drop resulting from the inrush current must not cause the voltage to fall below % of the supply voltage. Wire cross sections of max.. mm can be connected to the terminals of the brake control systems. Intermediate terminals must be used in case of larger cross sections. Keep the distance between the intermediate terminal and the brake control system as short as possible. Observe the voltage drop along the cable and particularly of the DC V brake coil when dimensioning the cross sections for the brake cable. The accelerator current is decisive for the calculation. The permitted tolerance for the rated voltage outside the range limit is ± %. GSE

Dimension sheets for asynchronous servomotors. Dimension sheets for asynchronous servomotors Dimension sheet information Observe the following notes regarding dimension sheets for asynchronous servomotors: The following dimension sheets show the sine encoder ESS / ESS / EVS. The other optional encoders ESR / ESR / EVR are the same size. The foot dimensions of CT, CVML and CV motors differ from IEC dimensions. Manual brake release can be pivoted through together with the terminal box, with the exception of CT.., CT.., CVM and CVL foot-mounted motors. With brake motors, please leave adequate room (= diameter of the fan guard) for removing the fan guard. CT.., CT.., CVM and CVL foot-mounted motors are not available with a flat-topped fan guard and must be supported if necessary. Motors from size CV.. are equipped with lifting eyebolts. The lifting eyebolts can be unscrewed. Leave a clearance of about half the fan guard diameter to allow for unhindered air inflow. The diameters of the fan guards on the following motors and brake motors are different when solid shaft encoders EV.. and AV.. are installed: CT and CT d = mm CT and CV d = mm CV and CVS d = mm CVM to CVM d = mm CVL to CV L d = mm GSE
