Product Description:

The PMB33C-20201-01 is a Servo Motor that belongs to the PMB Brushless Servomotors series of Pacific Scientific. It is manufactured by the company to serve industrial automation applications. It has a NEMA 34 Size motor frame for easy incorporation into the motor. It has a square key shaft type available in 2 and 3 sizes.

The PMB33C-20201-01 servo motor is equipped with a Hall Sensor for the position feedback to the rotor. The motor is provided with a 3.8 A winding. It supports flying leads with MS-style connectors for flexible connections. It is enclosed and shielded against external dust and rubble. It works well under tough and extreme conditions. The PMB33C-20201-01 servo motor has a brushless design construction for low maintenance. It operates in ambient temperatures from 0 to 40 degrees Celsius. It has a non-condensing relative humidity tolerance up to 95%. The motor is subjected to continuous vibration and mechanical shocks to test it. It has the capability of working at heights of up to 1 Km above sea level. It has a Class B insulation to make it safe and stable. This servo motor complies with the industry standards regarding its thermal and electrical safety.

The PMB33C-20201-01 servo motor has an inbuilt three-phase winding system. It assists in peak torque delivery during rapid acceleration. The Hall Sensor of the device offers precise commutation and motor synchronization. Its highest rating level of speed is about 5000 rpm. This is a servo motor with IP65 protection against dust and water jets. It can work reliably on an infinite number of load cycles. It works on a DC Bus rated approximately at 320 VDC. There are thermal sensors incorporated into the motor to prevent overheating.
