TORQUE, MOTOR PULL-UP: The minimum torque developed by a squirrel-cage or wound-rotor (slipring) motor during the period of acceleration from rest to the speed at which breakdown torque occurs. For squirrel-cage motors with 8% or greater slip, the pull-up torque, the break down torque, and the starting torque are all equal and occur at zero speed.

G.F: The manufacture of a wound-rotor synchronous motor requires dedicated coil winding and impregnation processes. The constraints of product performance expectations, the goal of reducing the weight-to-power ratio and the fast rate of production require us to effectively employ the most state-of-the-art technologies to perform those processes.

MENZEL slip ring motors, also called wound rotor motors, are available in all current motor cooling and protection types for low-voltage from 75 kW as well as medium and high voltage up to 15000 kW. They set technical standards in terms of size, performance, economy and reliability.
The wound-rotor motors use resistor to connect the rotor windings. The resistance can be adjusted to control the speed/torque characteristis of the motor. To use a variable frequency drive with a wound-rotor motor the resistors would need to be shorted. It is also recommended to use a dv/dt filter on the output of the drive to smooth the PWM.

compressor motors at two major gas plants in Saudi Arabia with 27,000 hp, 13.2 kV electric high-inertia motors. The high-inertia motor starting time can be longer than or closer to the specified safe stall time. Therefore, for these motors, thermal model analysis is critical for adequate stator and rotor protection. Rotor

MV and HV motors are extremely high quality and designed to offer years of trouble free operation. With Wound Rotor and Squirrel Cage options, can design and manufacture a motor to suit existing (drop in replacements) or new applications.
Wound Rotor Electric Motor Testing Wound rotor motors have a three-phase winding wound on the rotor which is connected to three phases of start-up resistors to provide current and speed control on start-up. Failed components in the resistor bank are common and often overlooked when troubleshooting.
Motors are tested at no load as per IEC 60034 standards and vibration values are maintained as per IEC 600816 standards. The test plant is capable to test the motors up to 20MW on no load from 1.1KV to 13.8Kv range of motors. All the motors under service undergoes crucial incoming inspection for mechanical and electrical test and result analysis.
Vacuum starters are offered in three classifications. They are NEMA rated devices up to 600 Vac, Special Purpose rated devices up to 1500 Vac and Mining rated devices rated up to 1500 Vac. Each device is tested to different standards to serve their market. Typical applications include full voltage control of three-phase squirrel cage motors, primary control of low-voltage wound rotor motors ...
TEAAC Enclosure / IC611 / IP54 - Siemens Type CAZ / 1RQ These horizontal, foot-mounted motors are designed for indoor and outdoor applications where internal parts must be protected from adverse ambient conditions.
motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat build-up generated during motor start-up. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor .
