The MST530G-0007-FT-N0CN-D303 Synchronous Torque Motor comes equipped with Winding type 0007 and cools down through the use of Liquid Cooling. The motor's frame length is G, which is correspondent to the amount of torque (The higher the length, the more torque. The IndraDyn T motors are always fitted with a stator-cooling jacket for operation with liquid cooling.

Product Description:
Bosch Rexroth Indramat introduced MST530G-0007-FT-N0CN-D303 that offers a rated velocity of 70 rpm with a rated power of 31 kW. The rated current drawn capacity of this motor is 96 A, and the maximum torque of this model is 9200 Nm. These machines have large poles as compared to other Bosch Rexroth Indramat motors. There are 70 poles in this motor, 35 south, and 35 north. The voltage constant at 20 C is 4400 V per minute.
The winding inductivity and resistance of this variant are 10.8 mH and 0.9 ohms. The component discharge capacity under windings is 50.7 nF. The stator mass of the machine MST530G-0007-FT-N0CN-D303 is 144 kg, and the power wire cross-section area is 2 x 16 mm2. The cross-section area of control wires in this model is 1.5 mm2. The diameter for cable connection is 2 x 9 mm with 0.3 mm tolerance. The cooling mode of MST530G-0007-FT-N0CN-D303 is liquid, and the encapsulation is with a cooling jacket. The motor has no encoder and the electrical connection is cable connected through the stator end with a bigger exterior diameter. This variant comes with a special design that is a wire lead out axially at the stator side with a greater exterior diameter and has no cable gland. The permissible temperature rate change of MST530G-0007-FT-N0CN-D303 is 0.5 C per minute.
The warning temperature of the winding of these synchronous torque motors is 145 C, and the shutdown temperature of the winding is 155 C. It is advised to stop the motor under such extreme environmental conditions. The allowed classes of ambient conditions during storage according to DIN EN 60721-3-1 under the air humidity category are from 1 - 29 g/m3 in absolute and 5 - 95 % in relative. The motors have built PTC temperature sensors for motor protection. In both cases of axial and radial, the maximum allowed shock load in 6 ms is 100 m/s2.
