Synchronous Torque Motor DST 

General technical data 

The torque motors of the DST series are permanently excited, high 

pole, water-cooled synchronous motors. 

The high torque densities in the low and medium speed ranges 

make this energy-efficient motor series ideal for use as a direct drive 

in general mechanical engineering applications. 

The drives have a high overload capability and display true running 

characteristics and are therefore ideal for sophisticated and dynamic 

applications. 

The integrated water-cooling system paves the way for optimal 

dissipation of losses with a high protection type. A fan is not required 

with these motors thus leading to a significant reduction in noise 

emissions. 

Moreover, these durable, compact motors are also largely 

maintenance-free, which is an extra benefit to ensure efficient 

operation.

Ratings definition 

The ratings (torques) listed in the table apply to continuous operation (S1) with nominal speed provided that the 

requirements that apply for the cooling circuit in liquid-cooled motors are observed (cf. P. 21)! 

Winding isolation and temperature rise 

The DST135/200/315 motors feature insulation class F in accordance with EN 60034 and have been designed for a 

permissible winding temperature of 105 K at a water intake temperature of up to 35°C. The DST260 features insulation 

class H in accordance with EN 60034 and has been designed for a permissible winding temperature of 125 K at a water 

intake temperature of up to 35°C. 

The insulation is resistant against gases and vapors of combustible materials and it meets the requirements expected of a 

moisture-proof and tropical insulation. 

Special insulation is necessary if concentrated acid vapors occur, if the permanent relative air humidity is more than 80% 

and as protection against termite and mould fungus attacks. 

In the case of converters with a DC link voltage > 500 V, the cables between the converter and the motor must not be 

longer than 20 meters. For longer cables, additional measures (e.g. motor filters) must be provided. The maximum 

permissible terminal voltage is 1000 V.

Bearings and shaft load 

All machines are equipped with rolling-contact bearings. On the solid-shaft version, the non-locating bearing is intended for 

the drive end and the locating bearing for the non-drive end. On the hollow-shaft version, it is the other way around.

Determination of radial forces FR 

When using pulleys, the radial load is calculated according to the following formula: 

PN = Nominal power in kW 

F 

R 

7 

2⋅10 

⋅P 

k 

n⋅D 

N 

= [N] 

n = Nominal speed in rpm 

D = Pulley diameter in mm 

The belt tightening factor k is approximately: 

k = 1.8...2.5 for V-belt 

k = 2.2..3.5 for flat belt 

(Observe specifications of the belt manufacturer) 

To ensure safe and reliable torque transmission, it is necessary to utilize the entire bearing length of the key. Otherwise, the 

key may be subjected to an excessive compressive load per unit area, which in turn can result in the failure of the motor. 

The pulley must be mounted up to the shaft shoulder and only tightened to the following maximum tightening torques. 

Gland M12 M16 M20 M24 

Tightening torque 33.0 Nm 80 Nm 160 Nm 255 Nm 

Permissible radial forces FR at the shaft end 

The ball bearings have been dimensioned for a calculated service life of approx. 20,000 operating hours 1) . The load values 

specified below must not be exceeded. The specified permissible radial forces FR are only valid for horizontal mounting of 

the motor without additional axial forces. If additional axial forces are involved, please consult the manufacturer. 

Axial load on the motor shaft 

When mounting clutches, pulleys, etc. onto the motor shaft, no axial forces must be applied! Therefore, use the internal 

thread of the shaft end as an assembly aid. 

1 ) Average operating temperature < 90°C

Case A – Ball bearing: 

The radial force Fr of the application is used to determine the possible maximum speed of the bearing in the 

“Ball bearing” characteristic. 

Radial force 1100 N => maximum speed 3250 rpm 

The maximum transmittable torque is based on the “Shaft” characteristic. 

Radial force 1100 N => maximum transmittable torque 450 Nm 

Case B – Roller bearing: 

The radial force Fr of the application is used to determine the possible maximum speed of the bearing in the 

“Roller bearing” characteristic. 

Radial force 4300 N => maximum speed 1500 rpm 

The maximum transmittable torque is based on the “Shaft” characteristic. 

Radial force 4300 N => maximum transmittable torque 345 Nm 

The roller bearing requires a minimum radial force of 800 N to avoid bearing damage.

Encoder cables 

General 

A fully preassembled encoder cable is used for all encoder systems. The connection on the motor side takes 

the form of a 12-pin round signal connector in the case of a resolver and SRS/SRM 50 or a 17-pin round signal 

connector in the case of the ECN 1313/EQN 132. The connection on the controller side takes the form of a 15pin 

SUB-D connector. 

The encoder cables are available in 'trailing' or 'non-trailing' versions. The trailing cable is suitable for use in 

trailing chains, for example. In contrast to the 'non-trailing' cable, which has a PVC sheath, the cable sheath for 

the trailing version consists of tougher PU for use in environments containing acids and bases (coolants). 

Cables can be supplied cut to lengths of complete meters (1 m, 2 m, 10 m) up to a maximum of 10 m. If lengths 

in excess of 10 m are required, cables can be supplied cut at 5 m intervals (10 m, 15 m, etc.).
