    Tips: Three-phase induction motor’s starting mode
    1. Direct starting
    This kind of starting mode is the most basic and simplest in the motor starting. First, the knife switch is used to connect the motor to the power grid and the motor starts to run under the rated voltage, which is characterized by less investment, simple equipment and small quantity. Although the starting time is short, the torque is smaller at starting and the current is large, which is suitable for starting small capacity motors.
    2. Reduced-voltage starting
    The reduced-voltage starting method can be introduced into medium and large size asynchronous motors to restraint the starting current. When the motor finishes the starting, it will resume to full pressure working. However, the result of reduced-voltage starting will lower down the starting torque. Therefore, the reduced-voltage starting is only suitable for starting the motor under no-load or lightly loaded condition.
    3. Soft starting
    Soft starter is a new type control device whose main advantages include soft starting, light load and energy saving, and quickness. One of the most important features is that the electronic circuit is conducted in the silicon controlled rectifier of motor under the tandem connection of power supply. When starting in this way, the torque of motor will gradually increase with enhancive speed.

    Existing reviews of 7.5 hp (5.5kW) 3 phase 2 pole AC Induction Motor
    Can you send me some information about these motors/ controllers?
    We are designing some tools for the offshore installation of windmills.
    For one of these tools I am looking for a HPU with two motors of each 5kW. The HPU needs to be battery powered. So I am looking for a system of e.g. 48V.
    The ambient temperature where the system needs to work is from -10 to 45 ℃ degrees since this is a salt laden environment. I am thinking to place these motors inside a box, but that box will be placed outside naturally.
    When the system is in operation, it is possible to put some coolers on the box. But when the system is off, it will need to survive the environmental temperatures.
    I’ve found your motors on the internet.
    Can they be used in such an environment and what would be the radiated energy from the motor and controller?
    Can you send me some information about these motors/ controllers?

    We also need to know: what are the required motor parameters?
    What is the voltage?
    What is the speed?
    With brakes and a gearbox?
    How much torque is needed?
    The use of induction motors
    Can I use your planetary gearbox on a 10KW 3ph 415 V induction motor?
