Technical definitions for pole-changing motors
■
概述
一般信息
Mechanically, all pole-changing motors correspond to the
single-speed motors. Pole-changing motors in frame size 225
并且在2极电平的上方具有相同的轴承和
same shaft extensions as the corresponding frame sizes of the
single-speed 2-pole motors.
电压和频率
The pole-changing motors in this catalog are supplied for the
following voltages in 50 Hz supply systems: 400 V, 500 V or
690 V.
在这些电压的范围内,可以提供电机
所需任何额定电压的异常绕组。被评级
voltages below 400 V as well as different frequencies, it is
询问至关重要。
Power
The power ratings specified in the selection tables apply to
根据EN 60034-1的义型S1。
关于40°C以上的冷却剂温度
installation altitudes above 1000 m above sea level, the same
积分适用于单速电机。
扭矩
杆状电动机可以从静止开始
whatever the number of poles. In the power rating tables, the
starting torques are specified for direct switch-on and the rotor
课程。高速水平可以具有拉出扭矩;所以
必须以较低的速度执行可能的启动
水平。结果改善了,并且沉重的开始
温度升高降低。
磁极额定值表中包含的杆状电动机
are supplied for 2 or 3 fixed speed levels.
If power levels are required other than those listed in the catalog,
也可以提供大兰电路电路的电机
2 separate windings. The power will, however, be considerably
lower than for a motor with a Dahlander circuit. The following
变体可用:
