Product Description

According to ATEX standards, the MKE118B-058-DP1-KE4 is a Rexroth Indramat MKE synchronous servo motor designed for use in potentially hazardous areas. As with other MKE motors, this unit is characterized by top-notch operational reliability, overload protection, maintenance-free operations, high dynamics, easy startup, and electrical commutation. In addition, it is equipped with a shaft with a sealing ring and a keyway. The insulation class of the MKE118B-058-DP1-KE4 is 155, and it complies with the IP 65 protection category. This motor has a max. velocity of 4,500 RPM and its winding inductivity is rated at 0.170 mH. It has a maximum torque of 102.0 Nm and a thermal time constant of 1.5 hours.

The MKE118B-058-DP1-KE4 features an optical encoder (multiturn-absolute EnDat 2.1) with 2,048 increments that helps to control the position and/or speed of the motor. In addition, this encoder is equipped with a data memory that stores the motor and control loop parameters. The resolution of the encoder is 13-bit, it has a maximum current consumption of 250 mA, and its maximum speed is rated at 12,000 min^-1. Generally, some variants of the MKE motors are equipped with a holding brake, and this model belongs to that category. Its holding brake has a holding torque of 32 Nm and a rated voltage of 24 Volts. The rated current of the holding brake is 0.93 Amperes, its moment of inertia is 0.001242 kgm², and connection & disconnection time are 15 ms and 115 ms, respectively.

The nominal data and motor performance of the MKE118B-058-DP1-KE4 are valid at an ambient operating temperature range of 0 – 40 degrees C. Also, the recommended installation height of this unit is within the range of 0 – 1000 meters above sea level. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
