Product Description
Coming from a noteworthy Rexroth motor series, the MAD100C-0250-SA-S2-KK0-05-N1 is an efficient AC asynchronous motor suitable for all rotary drive tasks. With its axially mounted surface fan, the machine has a relatively low thermal constant at 20 minutes. The thermal time constant for asynchronous motors represents the time at which the motor reaches around 63% of its steady-state temperature value. Rexroth Bosch recommends waiting for at least five times the thermal time constant to ensure that the motor has already cooled sufficiently after continuous operation. The MAD100C-0250-SA-S2-KK0-05-N1 operates at an ambient temperature of 0 to 40 degrees Celsius and features a thermal class insulation of 155.
The corresponding torque constant for the MAD100C-0250-SA-S2-KK0-05-N1 is 1.67 Nm/A, implying that for every one ampere increase of the input current, the output torque theoretically increases by 1.67 Nm. During stall or locked-rotor conditions, the machine exhibits the following values: 42 Nm and 28.8 A. These parameters represent the approximate values during the motor's starting periods and provide a basis for designing the machine's protection system. In terms of its nameplate ratings, the MAD100C-0250-SA-S2-KK0-05-N1 has a rated power of 10.47 kW, a base speed of 2500 rpm, an average RMS current of 27.8 A, and a nominal torque of 40 Nm.
Most asynchronous motors by Rexroth Bosch feature motor encoders that monitor certain parameters during operation. Usually, motor encoders measure the rotary position, speed, or angular displacement. The MAD100C-0250-SA-S2-KK0-05-N1 particularly uses an absolute singleturn encoder that samples at 2048 increments. During operation, this encoder sends digital signals to another controller that can perform certain actions to adjust the motor's operating point. The motor encoder, along with an efficient motor controller, creates an efficient control system necessary for automating processes and ensuring accuracy of motor performance.
