YZP series crane and metallurgical VVVF three-phase asynchronous motors based system can achieve variable speed frequency control devices for power supply speed three-phase asynchronous motor with frequency conversion device; achieve energy savings and control automationpurposes. With high efficiency, wide range of speed, accuracy, stable operation of braking and overload range, especially for applications that require variable frequency tone, short-term or intermittent cycle run frequent starting and braking of the occasion. Motor basic technical requirements to meet the requirements of IEC34-1 and GB755 Standard mounting dimensions conform to international standards IEC72.The motor can be attached to the installed thermal protection, heater, encoder, electromagnetic brake, speed switch and tachogenerator attachments to meet the demand for user support.
For example: YZP 250M1-4
Y: three-phase asynchronous motor
Z: For crane and metallurgical USES
250: Center Height (mm)
M1: The first core length of the medium-sized base
4: Pole number
