Easy Operation
AC motors include single-Phase motors used with a single-phase power supply and three-phase motors used with a three-phase power supply. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor does not require a capacitor. All you need is to connect the motor directly to a three-phase power supply.
The Power Supply Frequency Determines the Speed
The basic speed (synchronous speed) of a standard AC motor is determined by the power supply frequency and the number of poles. Many of our standard AC motors have four poles, so their synchronous speed is as follows:
- 50 Hz: 1500 r/min
- 60 Hz: 1800 r/min
The actual speed varies according to the load torque.
With our motors, the speed roughly falls within the following ranges at a load torque equivalent to the rated torque:
- 50 Hz: 1200 to 1300 r/min
- 60 Hz: 1450 to 1600 r/min
The rated speed of our standard AC motors are set within the above ranges and shown in each motor's specifications. To calculate a more accurate machine speed, use the rated speed as a reference.
the power supply frequency varies from region to region. In the case of automated equipment used in different regions, change the gear ratio of the gearhead or take the appropriate measure to obtain the desired speed.
Induction Motors
These motors can be easily operated from an AC power supply. Single-phase and three-phase motors are available.
Reversible Motors
Generating a greater starting torque and having a built-in friction brake, these single-phase motors allow for instantaneous switching of rotation direction.
Electromagnetic Brake Motors
These motors adopt a power off activated type electromagnetic brake to hold the load in position when the power is cut off.
Watertight, Dust-Resistant Motors
Geared motors of excellent watertight, dust-resistant structure. These motors conform to the IEC standard IP67.
Synchronous Motors
A special rotor is used to provide rotation at a fixed speed in synchronization with the power supply frequency.
Low-Speed Synchronous Motors
Uses the same stator and rotor as stepping motors. The motor offers superb starting, stopping and reversing characteristics as well as synchronous operation.
Clutch & Brake Motors
Equipped with an electromagnetic clutch and brake at the motor output shaft. High frequency starting and stopping is possible while the motor is operating.
Torque Motors
A special rotor is used to provide large starting torque and sloping characteristics (torque is highest at zero speed and decreases steadily with increasing speed). The torque can be changed by changing the applied voltage.
AC Speed Control Motors
AC speed control motors employ a closed-loop control system by utilizing feedback from the built-in tachogenerator.
